-## Migration Guide from v2 -> v3
-
-Version 3 adds several new, frequently requested features.  To do so, it introduces a few breaking changes.  We've worked to keep these as minimal as possible.  This guide explains the breaking changes and how you can quickly update your code.
-
-### `Token.Claims` is now an interface type
-
-The most requested feature from the 2.0 verison of this library was the ability to provide a custom type to the JSON parser for claims. This was implemented by introducing a new interface, `Claims`, to replace `map[string]interface{}`.  We also included two concrete implementations of `Claims`: `MapClaims` and `StandardClaims`.
-
-`MapClaims` is an alias for `map[string]interface{}` with built in validation behavior.  It is the default claims type when using `Parse`.  The usage is unchanged except you must type cast the claims property.
-
-The old example for parsing a token looked like this..
-
-```go
-	if token, err := jwt.Parse(tokenString, keyLookupFunc); err == nil {
-		fmt.Printf("Token for user %v expires %v", token.Claims["user"], token.Claims["exp"])
-	}
-```
-
-is now directly mapped to...
-
-```go
-	if token, err := jwt.Parse(tokenString, keyLookupFunc); err == nil {
-		claims := token.Claims.(jwt.MapClaims)
-		fmt.Printf("Token for user %v expires %v", claims["user"], claims["exp"])
-	}
-```
-
-`StandardClaims` is designed to be embedded in your custom type.  You can supply a custom claims type with the new `ParseWithClaims` function.  Here's an example of using a custom claims type.
-
-```go
-	type MyCustomClaims struct {
-		User string
-		*StandardClaims
-	}
-	
-	if token, err := jwt.ParseWithClaims(tokenString, &MyCustomClaims{}, keyLookupFunc); err == nil {
-		claims := token.Claims.(*MyCustomClaims)
-		fmt.Printf("Token for user %v expires %v", claims.User, claims.StandardClaims.ExpiresAt)
-	}
-```
-
-### `ParseFromRequest` has been moved
-
-To keep this library focused on the tokens without becoming overburdened with complex request processing logic, `ParseFromRequest` and its new companion `ParseFromRequestWithClaims` have been moved to a subpackage, `request`.  The method signatues have also been augmented to receive a new argument: `Extractor`.
-
-`Extractors` do the work of picking the token string out of a request.  The interface is simple and composable.
-
-This simple parsing example:
-
-```go
-	if token, err := jwt.ParseFromRequest(tokenString, req, keyLookupFunc); err == nil {
-		fmt.Printf("Token for user %v expires %v", token.Claims["user"], token.Claims["exp"])
-	}
-```
-
-is directly mapped to:
-
-```go
-	if token, err := request.ParseFromRequest(req, request.OAuth2Extractor, keyLookupFunc); err == nil {
-		claims := token.Claims.(jwt.MapClaims)
-		fmt.Printf("Token for user %v expires %v", claims["user"], claims["exp"])
-	}
-```
-
-There are several concrete `Extractor` types provided for your convenience:
-
-* `HeaderExtractor` will search a list of headers until one contains content.
-* `ArgumentExtractor` will search a list of keys in request query and form arguments until one contains content.
-* `MultiExtractor` will try a list of `Extractors` in order until one returns content.
-* `AuthorizationHeaderExtractor` will look in the `Authorization` header for a `Bearer` token.
-* `OAuth2Extractor` searches the places an OAuth2 token would be specified (per the spec): `Authorization` header and `access_token` argument
-* `PostExtractionFilter` wraps an `Extractor`, allowing you to process the content before it's parsed.  A simple example is stripping the `Bearer ` text from a header
-
-
-### RSA signing methods no longer accept `[]byte` keys
-
-Due to a [critical vulnerability](https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/), we've decided the convenience of accepting `[]byte` instead of `rsa.PublicKey` or `rsa.PrivateKey` isn't worth the risk of misuse.
-
-To replace this behavior, we've added two helper methods: `ParseRSAPrivateKeyFromPEM(key []byte) (*rsa.PrivateKey, error)` and `ParseRSAPublicKeyFromPEM(key []byte) (*rsa.PublicKey, error)`.  These are just simple helpers for unpacking PEM encoded PKCS1 and PKCS8 keys. If your keys are encoded any other way, all you need to do is convert them to the `crypto/rsa` package's types.
-
-```go 
-	func keyLookupFunc(*Token) (interface{}, error) {
-		// Don't forget to validate the alg is what you expect:
-		if _, ok := token.Method.(*jwt.SigningMethodRSA); !ok {
-			return nil, fmt.Errorf("Unexpected signing method: %v", token.Header["alg"])
-		}
-		
-		// Look up key 
-		key, err := lookupPublicKey(token.Header["kid"])
-		if err != nil {
-			return nil, err
-		}
-		
-		// Unpack key from PEM encoded PKCS8
-		return jwt.ParseRSAPublicKeyFromPEM(key)
-	}
-```

-**NEW VERSION COMING:** There have been a lot of improvements suggested since the version 3.0.0 released in 2016. I'm working now on cutting two different releases: 3.2.0 will contain any non-breaking changes or enhancements. 4.0.0 will follow shortly which will include breaking changes. See the 4.0.0 milestone to get an idea of what's coming. If you have other ideas, or would like to participate in 4.0.0, now's the time. If you depend on this library and don't want to be interrupted, I recommend you use your dependency mangement tool to pin to version 3. 
-
-**SECURITY NOTICE:** Some older versions of Go have a security issue in the cryotp/elliptic. Recommendation is to upgrade to at least 1.8.3. See issue #216 for more detail.
-
-**SECURITY NOTICE:** It's important that you [validate the `alg` presented is what you expect](https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/). This library attempts to make it easy to do the right thing by requiring key types match the expected alg, but you should take the extra step to verify it in your usage.  See the examples provided.
-
-## What the heck is a JWT?
-
-JWT.io has [a great introduction](https://jwt.io/introduction) to JSON Web Tokens.
-
-In short, it's a signed JSON object that does something useful (for example, authentication).  It's commonly used for `Bearer` tokens in Oauth 2.  A token is made of three parts, separated by `.`'s.  The first two parts are JSON objects, that have been [base64url](http://tools.ietf.org/html/rfc4648) encoded.  The last part is the signature, encoded the same way.
-
-The first part is called the header.  It contains the necessary information for verifying the last part, the signature.  For example, which encryption method was used for signing and what key was used.
-
-The part in the middle is the interesting bit.  It's called the Claims and contains the actual stuff you care about.  Refer to [the RFC](http://self-issued.info/docs/draft-jones-json-web-token.html) for information about reserved keys and the proper way to add your own.
-
-## What's in the box?
-
-This library supports the parsing and verification as well as the generation and signing of JWTs.  Current supported signing algorithms are HMAC SHA, RSA, RSA-PSS, and ECDSA, though hooks are present for adding your own.
-
-## Examples
-
-See [the project documentation](https://godoc.org/github.com/dgrijalva/jwt-go) for examples of usage:
-
-* [Simple example of parsing and validating a token](https://godoc.org/github.com/dgrijalva/jwt-go#example-Parse--Hmac)
-* [Simple example of building and signing a token](https://godoc.org/github.com/dgrijalva/jwt-go#example-New--Hmac)
-* [Directory of Examples](https://godoc.org/github.com/dgrijalva/jwt-go#pkg-examples)
-
-## Extensions
-
-This library publishes all the necessary components for adding your own signing methods.  Simply implement the `SigningMethod` interface and register a factory method using `RegisterSigningMethod`.  
-
-Here's an example of an extension that integrates with the Google App Engine signing tools: https://github.com/someone1/gcp-jwt-go
-
-## Compliance
-
-This library was last reviewed to comply with [RTF 7519](http://www.rfc-editor.org/info/rfc7519) dated May 2015 with a few notable differences:
-
-* In order to protect against accidental use of [Unsecured JWTs](http://self-issued.info/docs/draft-ietf-oauth-json-web-token.html#UnsecuredJWT), tokens using `alg=none` will only be accepted if the constant `jwt.UnsafeAllowNoneSignatureType` is provided as the key.
-
-## Project Status & Versioning
-
-This library is considered production ready.  Feedback and feature requests are appreciated.  The API should be considered stable.  There should be very few backwards-incompatible changes outside of major version updates (and only with good reason).
-
-This project uses [Semantic Versioning 2.0.0](http://semver.org).  Accepted pull requests will land on `master`.  Periodically, versions will be tagged from `master`.  You can find all the releases on [the project releases page](https://github.com/dgrijalva/jwt-go/releases).
-
-While we try to make it obvious when we make breaking changes, there isn't a great mechanism for pushing announcements out to users.  You may want to use this alternative package include: `gopkg.in/dgrijalva/jwt-go.v3`.  It will do the right thing WRT semantic versioning.
-
-**BREAKING CHANGES:*** 
-* Version 3.0.0 includes _a lot_ of changes from the 2.x line, including a few that break the API.  We've tried to break as few things as possible, so there should just be a few type signature changes.  A full list of breaking changes is available in `VERSION_HISTORY.md`.  See `MIGRATION_GUIDE.md` for more information on updating your code.
-
-## Usage Tips
-
-### Signing vs Encryption
-
-A token is simply a JSON object that is signed by its author. this tells you exactly two things about the data:
-
-* The author of the token was in the possession of the signing secret
-* The data has not been modified since it was signed
-
-It's important to know that JWT does not provide encryption, which means anyone who has access to the token can read its contents. If you need to protect (encrypt) the data, there is a companion spec, `JWE`, that provides this functionality. JWE is currently outside the scope of this library.
-
-### Choosing a Signing Method
-
-There are several signing methods available, and you should probably take the time to learn about the various options before choosing one.  The principal design decision is most likely going to be symmetric vs asymmetric.
-
-Symmetric signing methods, such as HSA, use only a single secret. This is probably the simplest signing method to use since any `[]byte` can be used as a valid secret. They are also slightly computationally faster to use, though this rarely is enough to matter. Symmetric signing methods work the best when both producers and consumers of tokens are trusted, or even the same system. Since the same secret is used to both sign and validate tokens, you can't easily distribute the key for validation.
-
-Asymmetric signing methods, such as RSA, use different keys for signing and verifying tokens. This makes it possible to produce tokens with a private key, and allow any consumer to access the public key for verification.
-
-### Signing Methods and Key Types
-
-Each signing method expects a different object type for its signing keys. See the package documentation for details. Here are the most common ones:
-
-* The [HMAC signing method](https://godoc.org/github.com/dgrijalva/jwt-go#SigningMethodHMAC) (`HS256`,`HS384`,`HS512`) expect `[]byte` values for signing and validation
-* The [RSA signing method](https://godoc.org/github.com/dgrijalva/jwt-go#SigningMethodRSA) (`RS256`,`RS384`,`RS512`) expect `*rsa.PrivateKey` for signing and `*rsa.PublicKey` for validation
-* The [ECDSA signing method](https://godoc.org/github.com/dgrijalva/jwt-go#SigningMethodECDSA) (`ES256`,`ES384`,`ES512`) expect `*ecdsa.PrivateKey` for signing and `*ecdsa.PublicKey` for validation
-
-### JWT and OAuth
-
-It's worth mentioning that OAuth and JWT are not the same thing. A JWT token is simply a signed JSON object. It can be used anywhere such a thing is useful. There is some confusion, though, as JWT is the most common type of bearer token used in OAuth2 authentication.
-
-Without going too far down the rabbit hole, here's a description of the interaction of these technologies:
-
-* OAuth is a protocol for allowing an identity provider to be separate from the service a user is logging in to. For example, whenever you use Facebook to log into a different service (Yelp, Spotify, etc), you are using OAuth.
-* OAuth defines several options for passing around authentication data. One popular method is called a "bearer token". A bearer token is simply a string that _should_ only be held by an authenticated user. Thus, simply presenting this token proves your identity. You can probably derive from here why a JWT might make a good bearer token.
-* Because bearer tokens are used for authentication, it's important they're kept secret. This is why transactions that use bearer tokens typically happen over SSL.
-
-## More
-
-Documentation can be found [on godoc.org](http://godoc.org/github.com/dgrijalva/jwt-go).
-
-The command line utility included in this project (cmd/jwt) provides a straightforward example of token creation and parsing as well as a useful tool for debugging your own integration. You'll also find several implementation examples in the documentation.

-## `jwt-go` Version History
-
-#### 3.2.0
-
-* Added method `ParseUnverified` to allow users to split up the tasks of parsing and validation
-* HMAC signing method returns `ErrInvalidKeyType` instead of `ErrInvalidKey` where appropriate
-* Added options to `request.ParseFromRequest`, which allows for an arbitrary list of modifiers to parsing behavior. Initial set include `WithClaims` and `WithParser`. Existing usage of this function will continue to work as before.
-* Deprecated `ParseFromRequestWithClaims` to simplify API in the future.
-
-#### 3.1.0
-
-* Improvements to `jwt` command line tool
-* Added `SkipClaimsValidation` option to `Parser`
-* Documentation updates
-
-#### 3.0.0
-
-* **Compatibility Breaking Changes**: See MIGRATION_GUIDE.md for tips on updating your code
-	* Dropped support for `[]byte` keys when using RSA signing methods.  This convenience feature could contribute to security vulnerabilities involving mismatched key types with signing methods.
-	* `ParseFromRequest` has been moved to `request` subpackage and usage has changed
-	* The `Claims` property on `Token` is now type `Claims` instead of `map[string]interface{}`.  The default value is type `MapClaims`, which is an alias to `map[string]interface{}`.  This makes it possible to use a custom type when decoding claims.
-* Other Additions and Changes
-	* Added `Claims` interface type to allow users to decode the claims into a custom type
-	* Added `ParseWithClaims`, which takes a third argument of type `Claims`.  Use this function instead of `Parse` if you have a custom type you'd like to decode into.
-	* Dramatically improved the functionality and flexibility of `ParseFromRequest`, which is now in the `request` subpackage
-	* Added `ParseFromRequestWithClaims` which is the `FromRequest` equivalent of `ParseWithClaims`
-	* Added new interface type `Extractor`, which is used for extracting JWT strings from http requests.  Used with `ParseFromRequest` and `ParseFromRequestWithClaims`.
-	* Added several new, more specific, validation errors to error type bitmask
-	* Moved examples from README to executable example files
-	* Signing method registry is now thread safe
-	* Added new property to `ValidationError`, which contains the raw error returned by calls made by parse/verify (such as those returned by keyfunc or json parser)
-
-#### 2.7.0
-
-This will likely be the last backwards compatible release before 3.0.0, excluding essential bug fixes.
-
-* Added new option `-show` to the `jwt` command that will just output the decoded token without verifying
-* Error text for expired tokens includes how long it's been expired
-* Fixed incorrect error returned from `ParseRSAPublicKeyFromPEM`
-* Documentation updates
-
-#### 2.6.0
-
-* Exposed inner error within ValidationError
-* Fixed validation errors when using UseJSONNumber flag
-* Added several unit tests
-
-#### 2.5.0
-
-* Added support for signing method none.  You shouldn't use this.  The API tries to make this clear.
-* Updated/fixed some documentation
-* Added more helpful error message when trying to parse tokens that begin with `BEARER `
-
-#### 2.4.0
-
-* Added new type, Parser, to allow for configuration of various parsing parameters
-	* You can now specify a list of valid signing methods.  Anything outside this set will be rejected.
-	* You can now opt to use the `json.Number` type instead of `float64` when parsing token JSON
-* Added support for [Travis CI](https://travis-ci.org/dgrijalva/jwt-go)
-* Fixed some bugs with ECDSA parsing
-
-#### 2.3.0
-
-* Added support for ECDSA signing methods
-* Added support for RSA PSS signing methods (requires go v1.4)
-
-#### 2.2.0
-
-* Gracefully handle a `nil` `Keyfunc` being passed to `Parse`.  Result will now be the parsed token and an error, instead of a panic.
-
-#### 2.1.0
-
-Backwards compatible API change that was missed in 2.0.0.
-
-* The `SignedString` method on `Token` now takes `interface{}` instead of `[]byte`
-
-#### 2.0.0
-
-There were two major reasons for breaking backwards compatibility with this update.  The first was a refactor required to expand the width of the RSA and HMAC-SHA signing implementations.  There will likely be no required code changes to support this change.
-
-The second update, while unfortunately requiring a small change in integration, is required to open up this library to other signing methods.  Not all keys used for all signing methods have a single standard on-disk representation.  Requiring `[]byte` as the type for all keys proved too limiting.  Additionally, this implementation allows for pre-parsed tokens to be reused, which might matter in an application that parses a high volume of tokens with a small set of keys.  Backwards compatibilty has been maintained for passing `[]byte` to the RSA signing methods, but they will also accept `*rsa.PublicKey` and `*rsa.PrivateKey`.
-
-It is likely the only integration change required here will be to change `func(t *jwt.Token) ([]byte, error)` to `func(t *jwt.Token) (interface{}, error)` when calling `Parse`.
-
-* **Compatibility Breaking Changes**
-	* `SigningMethodHS256` is now `*SigningMethodHMAC` instead of `type struct`
-	* `SigningMethodRS256` is now `*SigningMethodRSA` instead of `type struct`
-	* `KeyFunc` now returns `interface{}` instead of `[]byte`
-	* `SigningMethod.Sign` now takes `interface{}` instead of `[]byte` for the key
-	* `SigningMethod.Verify` now takes `interface{}` instead of `[]byte` for the key
-* Renamed type `SigningMethodHS256` to `SigningMethodHMAC`.  Specific sizes are now just instances of this type.
-    * Added public package global `SigningMethodHS256`
-    * Added public package global `SigningMethodHS384`
-    * Added public package global `SigningMethodHS512`
-* Renamed type `SigningMethodRS256` to `SigningMethodRSA`.  Specific sizes are now just instances of this type.
-    * Added public package global `SigningMethodRS256`
-    * Added public package global `SigningMethodRS384`
-    * Added public package global `SigningMethodRS512`
-* Moved sample private key for HMAC tests from an inline value to a file on disk.  Value is unchanged.
-* Refactored the RSA implementation to be easier to read
-* Exposed helper methods `ParseRSAPrivateKeyFromPEM` and `ParseRSAPublicKeyFromPEM`
-
-#### 1.0.2
-
-* Fixed bug in parsing public keys from certificates

-
-A Go (golang) port of the Ruby dotenv project (which loads env vars from a .env file)
-
-From the original Library:
-
-> Storing configuration in the environment is one of the tenets of a twelve-factor app. Anything that is likely to change between deployment environments–such as resource handles for databases or credentials for external services–should be extracted from the code into environment variables.
->
-> But it is not always practical to set environment variables on development machines or continuous integration servers where multiple projects are run. Dotenv load variables from a .env file into ENV when the environment is bootstrapped.
-
-It can be used as a library (for loading in env for your own daemons etc) or as a bin command.
-
-There is test coverage and CI for both linuxish and windows environments, but I make no guarantees about the bin version working on windows.
-
-## Installation
-
-As a library
-
-```shell
-go get github.com/joho/godotenv
-```
-
-or if you want to use it as a bin command
-```shell
-go get github.com/joho/godotenv/cmd/godotenv
-```
-
-## Usage
-
-Add your application configuration to your `.env` file in the root of your project:
-
-```shell
-S3_BUCKET=YOURS3BUCKET
-SECRET_KEY=YOURSECRETKEYGOESHERE
-```
-
-Then in your Go app you can do something like
-
-```go
-package main
-
-import (
-    "github.com/joho/godotenv"
-    "log"
-    "os"
-)
-
-func main() {
-  err := godotenv.Load()
-  if err != nil {
-    log.Fatal("Error loading .env file")
-  }
-
-  s3Bucket := os.Getenv("S3_BUCKET")
-  secretKey := os.Getenv("SECRET_KEY")
-
-  // now do something with s3 or whatever
-}
-```
-
-If you're even lazier than that, you can just take advantage of the autoload package which will read in `.env` on import
-
-```go
-import _ "github.com/joho/godotenv/autoload"
-```
-
-While `.env` in the project root is the default, you don't have to be constrained, both examples below are 100% legit
-
-```go
-_ = godotenv.Load("somerandomfile")
-_ = godotenv.Load("filenumberone.env", "filenumbertwo.env")
-```
-
-If you want to be really fancy with your env file you can do comments and exports (below is a valid env file)
-
-```shell
-# I am a comment and that is OK
-SOME_VAR=someval
-FOO=BAR # comments at line end are OK too
-export BAR=BAZ
-```
-
-Or finally you can do YAML(ish) style
-
-```yaml
-FOO: bar
-BAR: baz
-```
-
-as a final aside, if you don't want godotenv munging your env you can just get a map back instead
-
-```go
-var myEnv map[string]string
-myEnv, err := godotenv.Read()
-
-s3Bucket := myEnv["S3_BUCKET"]
-```
-
-... or from an `io.Reader` instead of a local file
-
-```go
-reader := getRemoteFile()
-myEnv, err := godotenv.Parse(reader)
-```
-
-... or from a `string` if you so desire
-
-```go
-content := getRemoteFileContent()
-myEnv, err := godotenv.Unmarshal(content)
-```
-
-### Command Mode
-
-Assuming you've installed the command as above and you've got `$GOPATH/bin` in your `$PATH`
-
-```
-godotenv -f /some/path/to/.env some_command with some args
-```
-
-If you don't specify `-f` it will fall back on the default of loading `.env` in `PWD`
-
-### Writing Env Files
-
-Godotenv can also write a map representing the environment to a correctly-formatted and escaped file
-
-```go
-env, err := godotenv.Unmarshal("KEY=value")
-err := godotenv.Write(env, "./.env")
-```
-
-... or to a string
-
-```go
-env, err := godotenv.Unmarshal("KEY=value")
-content, err := godotenv.Marshal(env)
-```
-
-## Contributing
-
-Contributions are most welcome! The parser itself is pretty stupidly naive and I wouldn't be surprised if it breaks with edge cases.
-
-*code changes without tests will not be accepted*
-
-1. Fork it
-2. Create your feature branch (`git checkout -b my-new-feature`)
-3. Commit your changes (`git commit -am 'Added some feature'`)
-4. Push to the branch (`git push origin my-new-feature`)
-5. Create new Pull Request
-
-## Releases
-
-Releases should follow [Semver](http://semver.org/) though the first couple of releases are `v1` and `v1.1`.
-
-Use [annotated tags for all releases](https://github.com/joho/godotenv/issues/30). Example `git tag -a v1.2.1`
-
-## CI
-
-Linux: [![Build Status](https://travis-ci.org/joho/godotenv.svg?branch=master)](https://travis-ci.org/joho/godotenv) Windows: [![Build status](https://ci.appveyor.com/api/projects/status/9v40vnfvvgde64u4)](https://ci.appveyor.com/project/joho/godotenv)
-
-## Who?
-
-The original library [dotenv](https://github.com/bkeepers/dotenv) was written by [Brandon Keepers](http://opensoul.org/), and this port was done by [John Barton](https://johnbarton.co/) based off the tests/fixtures in the original library.

-# HttpRouter [![Build Status](https://travis-ci.org/julienschmidt/httprouter.svg?branch=master)](https://travis-ci.org/julienschmidt/httprouter) [![Coverage Status](https://coveralls.io/repos/github/julienschmidt/httprouter/badge.svg?branch=master)](https://coveralls.io/github/julienschmidt/httprouter?branch=master) [![GoDoc](https://godoc.org/github.com/julienschmidt/httprouter?status.svg)](http://godoc.org/github.com/julienschmidt/httprouter)
-
-HttpRouter is a lightweight high performance HTTP request router (also called *multiplexer* or just *mux* for short) for [Go](https://golang.org/).
-
-In contrast to the [default mux](https://golang.org/pkg/net/http/#ServeMux) of Go's `net/http` package, this router supports variables in the routing pattern and matches against the request method. It also scales better.
-
-The router is optimized for high performance and a small memory footprint. It scales well even with very long paths and a large number of routes. A compressing dynamic trie (radix tree) structure is used for efficient matching.
-
-## Features
-
-**Only explicit matches:** With other routers, like [`http.ServeMux`](https://golang.org/pkg/net/http/#ServeMux), a requested URL path could match multiple patterns. Therefore they have some awkward pattern priority rules, like *longest match* or *first registered, first matched*. By design of this router, a request can only match exactly one or no route. As a result, there are also no unintended matches, which makes it great for SEO and improves the user experience.
-
-**Stop caring about trailing slashes:** Choose the URL style you like, the router automatically redirects the client if a trailing slash is missing or if there is one extra. Of course it only does so, if the new path has a handler. If you don't like it, you can [turn off this behavior](https://godoc.org/github.com/julienschmidt/httprouter#Router.RedirectTrailingSlash).
-
-**Path auto-correction:** Besides detecting the missing or additional trailing slash at no extra cost, the router can also fix wrong cases and remove superfluous path elements (like `../` or `//`). Is [CAPTAIN CAPS LOCK](http://www.urbandictionary.com/define.php?term=Captain+Caps+Lock) one of your users? HttpRouter can help him by making a case-insensitive look-up and redirecting him to the correct URL.
-
-**Parameters in your routing pattern:** Stop parsing the requested URL path, just give the path segment a name and the router delivers the dynamic value to you. Because of the design of the router, path parameters are very cheap.
-
-**Zero Garbage:** The matching and dispatching process generates zero bytes of garbage. The only heap allocations that are made are building the slice of the key-value pairs for path parameters, and building new context and request objects (the latter only in the standard `Handler`/`HandlerFunc` API). In the 3-argument API, if the request path contains no parameters not a single heap allocation is necessary.
-
-**Best Performance:** [Benchmarks speak for themselves](https://github.com/julienschmidt/go-http-routing-benchmark). See below for technical details of the implementation.
-
-**No more server crashes:** You can set a [Panic handler](https://godoc.org/github.com/julienschmidt/httprouter#Router.PanicHandler) to deal with panics occurring during handling a HTTP request. The router then recovers and lets the `PanicHandler` log what happened and deliver a nice error page.
-
-**Perfect for APIs:** The router design encourages to build sensible, hierarchical RESTful APIs. Moreover it has built-in native support for [OPTIONS requests](http://zacstewart.com/2012/04/14/http-options-method.html) and `405 Method Not Allowed` replies.
-
-Of course you can also set **custom [`NotFound`](https://godoc.org/github.com/julienschmidt/httprouter#Router.NotFound) and  [`MethodNotAllowed`](https://godoc.org/github.com/julienschmidt/httprouter#Router.MethodNotAllowed) handlers** and [**serve static files**](https://godoc.org/github.com/julienschmidt/httprouter#Router.ServeFiles).
-
-## Usage
-
-This is just a quick introduction, view the [GoDoc](http://godoc.org/github.com/julienschmidt/httprouter) for details.
-
-Let's start with a trivial example:
-
-```go
-package main
-
-import (
-    "fmt"
-    "net/http"
-    "log"
-
-    "github.com/julienschmidt/httprouter"
-)
-
-func Index(w http.ResponseWriter, r *http.Request, _ httprouter.Params) {
-    fmt.Fprint(w, "Welcome!\n")
-}
-
-func Hello(w http.ResponseWriter, r *http.Request, ps httprouter.Params) {
-    fmt.Fprintf(w, "hello, %s!\n", ps.ByName("name"))
-}
-
-func main() {
-    router := httprouter.New()
-    router.GET("/", Index)
-    router.GET("/hello/:name", Hello)
-
-    log.Fatal(http.ListenAndServe(":8080", router))
-}
-```
-
-### Named parameters
-
-As you can see, `:name` is a *named parameter*. The values are accessible via `httprouter.Params`, which is just a slice of `httprouter.Param`s. You can get the value of a parameter either by its index in the slice, or by using the `ByName(name)` method: `:name` can be retrieved by `ByName("name")`.
-
-When using a `http.Handler` (using `router.Handler` or `http.HandlerFunc`) instead of HttpRouter's handle API using a 3rd function parameter, the named parameters are stored in the `request.Context`. See more below under [Why doesn't this work with http.Handler?](#why-doesnt-this-work-with-httphandler).
-
-Named parameters only match a single path segment:
-
-```
-Pattern: /user/:user
-
- /user/gordon              match
- /user/you                 match
- /user/gordon/profile      no match
- /user/                    no match
-```
-
-**Note:** Since this router has only explicit matches, you can not register static routes and parameters for the same path segment. For example you can not register the patterns `/user/new` and `/user/:user` for the same request method at the same time. The routing of different request methods is independent from each other.
-
-### Catch-All parameters
-
-The second type are *catch-all* parameters and have the form `*name`. Like the name suggests, they match everything. Therefore they must always be at the **end** of the pattern:
-
-```
-Pattern: /src/*filepath
-
- /src/                     match
- /src/somefile.go          match
- /src/subdir/somefile.go   match
-```
-
-## How does it work?
-
-The router relies on a tree structure which makes heavy use of *common prefixes*, it is basically a *compact* [*prefix tree*](https://en.wikipedia.org/wiki/Trie) (or just [*Radix tree*](https://en.wikipedia.org/wiki/Radix_tree)). Nodes with a common prefix also share a common parent. Here is a short example what the routing tree for the `GET` request method could look like:
-
-```
-Priority   Path             Handle
-9          \                *<1>
-3          ├s               nil
-2          |├earch\         *<2>
-1          |└upport\        *<3>
-2          ├blog\           *<4>
-1          |    └:post      nil
-1          |         └\     *<5>
-2          ├about-us\       *<6>
-1          |        └team\  *<7>
-1          └contact\        *<8>
-```
-
-Every `*<num>` represents the memory address of a handler function (a pointer). If you follow a path trough the tree from the root to the leaf, you get the complete route path, e.g `\blog\:post\`, where `:post` is just a placeholder ([*parameter*](#named-parameters)) for an actual post name. Unlike hash-maps, a tree structure also allows us to use dynamic parts like the `:post` parameter, since we actually match against the routing patterns instead of just comparing hashes. [As benchmarks show](https://github.com/julienschmidt/go-http-routing-benchmark), this works very well and efficient.
-
-Since URL paths have a hierarchical structure and make use only of a limited set of characters (byte values), it is very likely that there are a lot of common prefixes. This allows us to easily reduce the routing into ever smaller problems. Moreover the router manages a separate tree for every request method. For one thing it is more space efficient than holding a method->handle map in every single node, it also allows us to greatly reduce the routing problem before even starting the look-up in the prefix-tree.
-
-For even better scalability, the child nodes on each tree level are ordered by priority, where the priority is just the number of handles registered in sub nodes (children, grandchildren, and so on..). This helps in two ways:
-
-1. Nodes which are part of the most routing paths are evaluated first. This helps to make as much routes as possible to be reachable as fast as possible.
-2. It is some sort of cost compensation. The longest reachable path (highest cost) can always be evaluated first. The following scheme visualizes the tree structure. Nodes are evaluated from top to bottom and from left to right.

-
-## Why doesn't this work with `http.Handler`?
-
-**It does!** The router itself implements the `http.Handler` interface. Moreover the router provides convenient [adapters for `http.Handler`](https://godoc.org/github.com/julienschmidt/httprouter#Router.Handler)s and [`http.HandlerFunc`](https://godoc.org/github.com/julienschmidt/httprouter#Router.HandlerFunc)s which allows them to be used as a [`httprouter.Handle`](https://godoc.org/github.com/julienschmidt/httprouter#Router.Handle) when registering a route.
-
-Named parameters can be accessed `request.Context`:
-
-```go
-func Hello(w http.ResponseWriter, r *http.Request) {
-    params := httprouter.ParamsFromContext(r.Context())
-
-    fmt.Fprintf(w, "hello, %s!\n", params.ByName("name"))
-}
-```
-
-Alternatively, one can also use `params := r.Context().Value(httprouter.ParamsKey)` instead of the helper function.
-
-Just try it out for yourself, the usage of HttpRouter is very straightforward. The package is compact and minimalistic, but also probably one of the easiest routers to set up.
-
-## Automatic OPTIONS responses and CORS
-
-One might wish to modify automatic responses to OPTIONS requests, e.g. to support [CORS preflight requests](https://developer.mozilla.org/en-US/docs/Glossary/preflight_request) or to set other headers.
-This can be achieved using the [`Router.GlobalOPTIONS`](https://godoc.org/github.com/julienschmidt/httprouter#Router.GlobalOPTIONS) handler:
-
-```go
-router.GlobalOPTIONS = http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
-    if r.Header.Get("Access-Control-Request-Method") != "" {
-        // Set CORS headers
-        header := w.Header()
-        header.Set("Access-Control-Allow-Methods", r.Header.Get("Allow"))
-        header.Set("Access-Control-Allow-Origin", "*")
-    }
-
-    // Adjust status code to 204
-    w.WriteHeader(http.StatusNoContent)
-})
-```
-
-## Where can I find Middleware *X*?
-
-This package just provides a very efficient request router with a few extra features. The router is just a [`http.Handler`](https://golang.org/pkg/net/http/#Handler), you can chain any http.Handler compatible middleware before the router, for example the [Gorilla handlers](http://www.gorillatoolkit.org/pkg/handlers). Or you could [just write your own](https://justinas.org/writing-http-middleware-in-go/), it's very easy!
-
-Alternatively, you could try [a web framework based on HttpRouter](#web-frameworks-based-on-httprouter).
-
-### Multi-domain / Sub-domains
-
-Here is a quick example: Does your server serve multiple domains / hosts?
-You want to use sub-domains?
-Define a router per host!
-
-```go
-// We need an object that implements the http.Handler interface.
-// Therefore we need a type for which we implement the ServeHTTP method.
-// We just use a map here, in which we map host names (with port) to http.Handlers
-type HostSwitch map[string]http.Handler
-
-// Implement the ServeHTTP method on our new type
-func (hs HostSwitch) ServeHTTP(w http.ResponseWriter, r *http.Request) {
-	// Check if a http.Handler is registered for the given host.
-	// If yes, use it to handle the request.
-	if handler := hs[r.Host]; handler != nil {
-		handler.ServeHTTP(w, r)
-	} else {
-		// Handle host names for which no handler is registered
-		http.Error(w, "Forbidden", 403) // Or Redirect?
-	}
-}
-
-func main() {
-	// Initialize a router as usual
-	router := httprouter.New()
-	router.GET("/", Index)
-	router.GET("/hello/:name", Hello)
-
-	// Make a new HostSwitch and insert the router (our http handler)
-	// for example.com and port 12345
-	hs := make(HostSwitch)
-	hs["example.com:12345"] = router
-
-	// Use the HostSwitch to listen and serve on port 12345
-	log.Fatal(http.ListenAndServe(":12345", hs))
-}
-```
-
-### Basic Authentication
-
-Another quick example: Basic Authentication (RFC 2617) for handles:
-
-```go
-package main
-
-import (
-	"fmt"
-	"log"
-	"net/http"
-
-	"github.com/julienschmidt/httprouter"
-)
-
-func BasicAuth(h httprouter.Handle, requiredUser, requiredPassword string) httprouter.Handle {
-	return func(w http.ResponseWriter, r *http.Request, ps httprouter.Params) {
-		// Get the Basic Authentication credentials
-		user, password, hasAuth := r.BasicAuth()
-
-		if hasAuth && user == requiredUser && password == requiredPassword {
-			// Delegate request to the given handle
-			h(w, r, ps)
-		} else {
-			// Request Basic Authentication otherwise
-			w.Header().Set("WWW-Authenticate", "Basic realm=Restricted")
-			http.Error(w, http.StatusText(http.StatusUnauthorized), http.StatusUnauthorized)
-		}
-	}
-}
-
-func Index(w http.ResponseWriter, r *http.Request, _ httprouter.Params) {
-	fmt.Fprint(w, "Not protected!\n")
-}
-
-func Protected(w http.ResponseWriter, r *http.Request, _ httprouter.Params) {
-	fmt.Fprint(w, "Protected!\n")
-}
-
-func main() {
-	user := "gordon"
-	pass := "secret!"
-
-	router := httprouter.New()
-	router.GET("/", Index)
-	router.GET("/protected/", BasicAuth(Protected, user, pass))
-
-	log.Fatal(http.ListenAndServe(":8080", router))
-}
-```
-
-## Chaining with the NotFound handler
-
-**NOTE: It might be required to set [`Router.HandleMethodNotAllowed`](https://godoc.org/github.com/julienschmidt/httprouter#Router.HandleMethodNotAllowed) to `false` to avoid problems.**
-
-You can use another [`http.Handler`](https://golang.org/pkg/net/http/#Handler), for example another router, to handle requests which could not be matched by this router by using the [`Router.NotFound`](https://godoc.org/github.com/julienschmidt/httprouter#Router.NotFound) handler. This allows chaining.
-
-### Static files
-
-The `NotFound` handler can for example be used to serve static files from the root path `/` (like an `index.html` file along with other assets):
-
-```go
-// Serve static files from the ./public directory
-router.NotFound = http.FileServer(http.Dir("public"))
-```
-
-But this approach sidesteps the strict core rules of this router to avoid routing problems. A cleaner approach is to use a distinct sub-path for serving files, like `/static/*filepath` or `/files/*filepath`.
-
-## Web Frameworks based on HttpRouter
-
-If the HttpRouter is a bit too minimalistic for you, you might try one of the following more high-level 3rd-party web frameworks building upon the HttpRouter package:

-// Package httprouter is a trie based high performance HTTP request router.
-//
-// A trivial example is:
-//
-//  package main
-//
-//  import (
-//      "fmt"
-//      "github.com/julienschmidt/httprouter"
-//      "net/http"
-//      "log"
-//  )
-//
-//  func Index(w http.ResponseWriter, r *http.Request, _ httprouter.Params) {
-//      fmt.Fprint(w, "Welcome!\n")
-//  }
-//
-//  func Hello(w http.ResponseWriter, r *http.Request, ps httprouter.Params) {
-//      fmt.Fprintf(w, "hello, %s!\n", ps.ByName("name"))
-//  }
-//
-//  func main() {
-//      router := httprouter.New()
-//      router.GET("/", Index)
-//      router.GET("/hello/:name", Hello)
-//
-//      log.Fatal(http.ListenAndServe(":8080", router))
-//  }
-//
-// The router matches incoming requests by the request method and the path.
-// If a handle is registered for this path and method, the router delegates the
-// request to that function.
-// For the methods GET, POST, PUT, PATCH and DELETE shortcut functions exist to
-// register handles, for all other methods router.Handle can be used.
-//
-// The registered path, against which the router matches incoming requests, can
-// contain two types of parameters:
-//  Syntax    Type
-//  :name     named parameter
-//  *name     catch-all parameter
-//
-// Named parameters are dynamic path segments. They match anything until the
-// next '/' or the path end:
-//  Path: /blog/:category/:post
-//
-//  Requests:
-//   /blog/go/request-routers            match: category="go", post="request-routers"
-//   /blog/go/request-routers/           no match, but the router would redirect
-//   /blog/go/                           no match
-//   /blog/go/request-routers/comments   no match
-//
-// Catch-all parameters match anything until the path end, including the
-// directory index (the '/' before the catch-all). Since they match anything
-// until the end, catch-all parameters must always be the final path element.
-//  Path: /files/*filepath
-//
-//  Requests:
-//   /files/                             match: filepath="/"
-//   /files/LICENSE                      match: filepath="/LICENSE"
-//   /files/templates/article.html       match: filepath="/templates/article.html"
-//   /files                              no match, but the router would redirect
-//
-// The value of parameters is saved as a slice of the Param struct, consisting
-// each of a key and a value. The slice is passed to the Handle func as a third
-// parameter.
-// There are two ways to retrieve the value of a parameter:
-//  // by the name of the parameter
-//  user := ps.ByName("user") // defined by :user or *user
-//
-//  // by the index of the parameter. This way you can also get the name (key)
-//  thirdKey   := ps[2].Key   // the name of the 3rd parameter
-//  thirdValue := ps[2].Value // the value of the 3rd parameter

-
-[![GoDoc](https://godoc.org/github.com/lib/pq?status.svg)](https://pkg.go.dev/github.com/lib/pq?tab=doc)
-
-## Install
-
-	go get github.com/lib/pq
-
-## Features
-
-* SSL
-* Handles bad connections for `database/sql`
-* Scan `time.Time` correctly (i.e. `timestamp[tz]`, `time[tz]`, `date`)
-* Scan binary blobs correctly (i.e. `bytea`)
-* Package for `hstore` support
-* COPY FROM support
-* pq.ParseURL for converting urls to connection strings for sql.Open.
-* Many libpq compatible environment variables
-* Unix socket support
-* Notifications: `LISTEN`/`NOTIFY`
-* pgpass support
-* GSS (Kerberos) auth
-
-## Tests
-
-`go test` is used for testing.  See [TESTS.md](TESTS.md) for more details.
-
-## Status
-
-This package is effectively in maintenance mode and is not actively developed. Small patches and features are only rarely reviewed and merged. We recommend using [pgx](https://github.com/jackc/pgx) which is actively maintained.

-# Tests
-
-## Running Tests
-
-`go test` is used for testing. A running PostgreSQL
-server is required, with the ability to log in. The
-database to connect to test with is "pqgotest," on
-"localhost" but these can be overridden using [environment
-variables](https://www.postgresql.org/docs/9.3/static/libpq-envars.html).
-
-Example:
-
-	PGHOST=/run/postgresql go test
-
-## Benchmarks
-
-A benchmark suite can be run as part of the tests:
-
-	go test -bench .
-
-## Example setup (Docker)
-
-Run a postgres container:
-
-```
-docker run --expose 5432:5432 postgres
-```
-
-Run tests:
-
-```
-PGHOST=localhost PGPORT=5432 PGUSER=postgres PGSSLMODE=disable PGDATABASE=postgres go test
-```

-/*
-Package pq is a pure Go Postgres driver for the database/sql package.
-
-In most cases clients will use the database/sql package instead of
-using this package directly. For example:
-
-	import (
-		"database/sql"
-
-		_ "github.com/lib/pq"
-	)
-
-	func main() {
-		connStr := "user=pqgotest dbname=pqgotest sslmode=verify-full"
-		db, err := sql.Open("postgres", connStr)
-		if err != nil {
-			log.Fatal(err)
-		}
-
-		age := 21
-		rows, err := db.Query("SELECT name FROM users WHERE age = $1", age)
-		…
-	}
-
-You can also connect to a database using a URL. For example:
-
-	connStr := "postgres://pqgotest:password@localhost/pqgotest?sslmode=verify-full"
-	db, err := sql.Open("postgres", connStr)
-
-
-Connection String Parameters
-
-
-Similarly to libpq, when establishing a connection using pq you are expected to
-supply a connection string containing zero or more parameters.
-A subset of the connection parameters supported by libpq are also supported by pq.
-Additionally, pq also lets you specify run-time parameters (such as search_path or work_mem)
-directly in the connection string.  This is different from libpq, which does not allow
-run-time parameters in the connection string, instead requiring you to supply
-them in the options parameter.
-
-For compatibility with libpq, the following special connection parameters are
-supported:
-
-	* dbname - The name of the database to connect to
-	* user - The user to sign in as
-	* password - The user's password
-	* host - The host to connect to. Values that start with / are for unix
-	  domain sockets. (default is localhost)
-	* port - The port to bind to. (default is 5432)
-	* sslmode - Whether or not to use SSL (default is require, this is not
-	  the default for libpq)
-	* fallback_application_name - An application_name to fall back to if one isn't provided.
-	* connect_timeout - Maximum wait for connection, in seconds. Zero or
-	  not specified means wait indefinitely.
-	* sslcert - Cert file location. The file must contain PEM encoded data.
-	* sslkey - Key file location. The file must contain PEM encoded data.
-	* sslrootcert - The location of the root certificate file. The file
-	  must contain PEM encoded data.
-
-Valid values for sslmode are:
-
-	* disable - No SSL
-	* require - Always SSL (skip verification)
-	* verify-ca - Always SSL (verify that the certificate presented by the
-	  server was signed by a trusted CA)
-	* verify-full - Always SSL (verify that the certification presented by
-	  the server was signed by a trusted CA and the server host name
-	  matches the one in the certificate)
-
-See http://www.postgresql.org/docs/current/static/libpq-connect.html#LIBPQ-CONNSTRING
-for more information about connection string parameters.
-
-Use single quotes for values that contain whitespace:
-
-    "user=pqgotest password='with spaces'"
-
-A backslash will escape the next character in values:
-
-    "user=space\ man password='it\'s valid'"
-
-Note that the connection parameter client_encoding (which sets the
-text encoding for the connection) may be set but must be "UTF8",
-matching with the same rules as Postgres. It is an error to provide
-any other value.
-
-In addition to the parameters listed above, any run-time parameter that can be
-set at backend start time can be set in the connection string.  For more
-information, see
-http://www.postgresql.org/docs/current/static/runtime-config.html.
-
-Most environment variables as specified at http://www.postgresql.org/docs/current/static/libpq-envars.html
-supported by libpq are also supported by pq.  If any of the environment
-variables not supported by pq are set, pq will panic during connection
-establishment.  Environment variables have a lower precedence than explicitly
-provided connection parameters.
-
-The pgpass mechanism as described in http://www.postgresql.org/docs/current/static/libpq-pgpass.html
-is supported, but on Windows PGPASSFILE must be specified explicitly.
-
-
-Queries
-
-
-database/sql does not dictate any specific format for parameter
-markers in query strings, and pq uses the Postgres-native ordinal markers,
-as shown above. The same marker can be reused for the same parameter:
-
-	rows, err := db.Query(`SELECT name FROM users WHERE favorite_fruit = $1
-		OR age BETWEEN $2 AND $2 + 3`, "orange", 64)
-
-pq does not support the LastInsertId() method of the Result type in database/sql.
-To return the identifier of an INSERT (or UPDATE or DELETE), use the Postgres
-RETURNING clause with a standard Query or QueryRow call:
-
-	var userid int
-	err := db.QueryRow(`INSERT INTO users(name, favorite_fruit, age)
-		VALUES('beatrice', 'starfruit', 93) RETURNING id`).Scan(&userid)
-
-For more details on RETURNING, see the Postgres documentation:
-
-	http://www.postgresql.org/docs/current/static/sql-insert.html
-	http://www.postgresql.org/docs/current/static/sql-update.html
-	http://www.postgresql.org/docs/current/static/sql-delete.html
-
-For additional instructions on querying see the documentation for the database/sql package.
-
-
-Data Types
-
-
-Parameters pass through driver.DefaultParameterConverter before they are handled
-by this package. When the binary_parameters connection option is enabled,
-[]byte values are sent directly to the backend as data in binary format.
-
-This package returns the following types for values from the PostgreSQL backend:
-
-	- integer types smallint, integer, and bigint are returned as int64
-	- floating-point types real and double precision are returned as float64
-	- character types char, varchar, and text are returned as string
-	- temporal types date, time, timetz, timestamp, and timestamptz are
-	  returned as time.Time
-	- the boolean type is returned as bool
-	- the bytea type is returned as []byte
-
-All other types are returned directly from the backend as []byte values in text format.
-
-
-Errors
-
-
-pq may return errors of type *pq.Error which can be interrogated for error details:
-
-        if err, ok := err.(*pq.Error); ok {
-            fmt.Println("pq error:", err.Code.Name())
-        }
-
-See the pq.Error type for details.
-
-
-Bulk imports
-
-You can perform bulk imports by preparing a statement returned by pq.CopyIn (or
-pq.CopyInSchema) in an explicit transaction (sql.Tx). The returned statement
-handle can then be repeatedly "executed" to copy data into the target table.
-After all data has been processed you should call Exec() once with no arguments
-to flush all buffered data. Any call to Exec() might return an error which
-should be handled appropriately, but because of the internal buffering an error
-returned by Exec() might not be related to the data passed in the call that
-failed.
-
-CopyIn uses COPY FROM internally. It is not possible to COPY outside of an
-explicit transaction in pq.
-
-Usage example:
-
-	txn, err := db.Begin()
-	if err != nil {
-		log.Fatal(err)
-	}
-
-	stmt, err := txn.Prepare(pq.CopyIn("users", "name", "age"))
-	if err != nil {
-		log.Fatal(err)
-	}
-
-	for _, user := range users {
-		_, err = stmt.Exec(user.Name, int64(user.Age))
-		if err != nil {
-			log.Fatal(err)
-		}
-	}
-
-	_, err = stmt.Exec()
-	if err != nil {
-		log.Fatal(err)
-	}
-
-	err = stmt.Close()
-	if err != nil {
-		log.Fatal(err)
-	}
-
-	err = txn.Commit()
-	if err != nil {
-		log.Fatal(err)
-	}
-
-
-Notifications
-
-
-PostgreSQL supports a simple publish/subscribe model over database
-connections.  See http://www.postgresql.org/docs/current/static/sql-notify.html
-for more information about the general mechanism.
-
-To start listening for notifications, you first have to open a new connection
-to the database by calling NewListener.  This connection can not be used for
-anything other than LISTEN / NOTIFY.  Calling Listen will open a "notification
-channel"; once a notification channel is open, a notification generated on that
-channel will effect a send on the Listener.Notify channel.  A notification
-channel will remain open until Unlisten is called, though connection loss might
-result in some notifications being lost.  To solve this problem, Listener sends
-a nil pointer over the Notify channel any time the connection is re-established
-following a connection loss.  The application can get information about the
-state of the underlying connection by setting an event callback in the call to
-NewListener.
-
-A single Listener can safely be used from concurrent goroutines, which means
-that there is often no need to create more than one Listener in your
-application.  However, a Listener is always connected to a single database, so
-you will need to create a new Listener instance for every database you want to
-receive notifications in.
-
-The channel name in both Listen and Unlisten is case sensitive, and can contain
-any characters legal in an identifier (see
-http://www.postgresql.org/docs/current/static/sql-syntax-lexical.html#SQL-SYNTAX-IDENTIFIERS
-for more information).  Note that the channel name will be truncated to 63
-bytes by the PostgreSQL server.
-
-You can find a complete, working example of Listener usage at
-https://godoc.org/github.com/lib/pq/example/listen.
-
-
-Kerberos Support
-
-
-If you need support for Kerberos authentication, add the following to your main
-package:
-
-	import "github.com/lib/pq/auth/kerberos"
-
-	func init() {
-		pq.RegisterGSSProvider(func() (pq.Gss, error) { return kerberos.NewGSS() })
-	}
-
-This package is in a separate module so that users who don't need Kerberos
-don't have to download unnecessary dependencies.
-
-When imported, additional connection string parameters are supported:
-
-	* krbsrvname - GSS (Kerberos) service name when constructing the
-	  SPN (default is `postgres`). This will be combined with the host
-	  to form the full SPN: `krbsrvname/host`.
-	* krbspn - GSS (Kerberos) SPN. This takes priority over
-	  `krbsrvname` if present.

-
-[![Build Status](https://travis-ci.org/sideshow/apns2.svg?branch=master)](https://travis-ci.org/sideshow/apns2)  [![Coverage Status](https://coveralls.io/repos/sideshow/apns2/badge.svg?branch=master&service=github)](https://coveralls.io/github/sideshow/apns2?branch=master)  [![GoDoc](https://godoc.org/github.com/sideshow/apns2?status.svg)](https://godoc.org/github.com/sideshow/apns2)
-
-## Features
-
-- Uses new Apple APNs HTTP/2 connection
-- Fast - See [notes on speed](https://github.com/sideshow/apns2/wiki/APNS-HTTP-2-Push-Speed)
-- Works with go 1.7 and later
-- Supports new Apple Token Based Authentication (JWT)
-- Supports new iOS 10 features such as Collapse IDs, Subtitles and Mutable Notifications
-- Supports persistent connections to APNs
-- Supports VoIP/PushKit notifications (iOS 8 and later)
-- Modular & easy to use
-- Tested and working in APNs production environment
-
-## Install
-
-- Make sure you have [Go](https://golang.org/doc/install) installed and have set your [GOPATH](https://golang.org/doc/code.html#GOPATH).
-- Install apns2:
-
-```sh
-go get -u github.com/sideshow/apns2
-```
-
-If you are running the test suite you will also need to install testify:
-```sh
-go get -u github.com/stretchr/testify
-```
-
-## Example
-
-```go
-package main
-
-import (
-  "log"
-  "fmt"
-
-  "github.com/sideshow/apns2"
-  "github.com/sideshow/apns2/certificate"
-)
-
-func main() {
-
-  cert, err := certificate.FromP12File("../cert.p12", "")
-  if err != nil {
-    log.Fatal("Cert Error:", err)
-  }
-
-  notification := &apns2.Notification{}
-  notification.DeviceToken = "11aa01229f15f0f0c52029d8cf8cd0aeaf2365fe4cebc4af26cd6d76b7919ef7"
-  notification.Topic = "com.sideshow.Apns2"
-  notification.Payload = []byte(`{"aps":{"alert":"Hello!"}}`) // See Payload section below
-
-  client := apns2.NewClient(cert).Production()
-  res, err := client.Push(notification)
-
-  if err != nil {
-    log.Fatal("Error:", err)
-  }
-
-  fmt.Printf("%v %v %v\n", res.StatusCode, res.ApnsID, res.Reason)
-}
-```
-
-## JWT Token Example
-
-Instead of using a `.p12` or `.pem` certificate as above, you can optionally use
-APNs JWT _Provider Authentication Tokens_. First you will need a signing key (`.p8` file), Key ID and Team ID [from Apple](http://help.apple.com/xcode/mac/current/#/dev54d690a66). Once you have these details, you can create a new client:
-
-```go
-authKey, err := token.AuthKeyFromFile("../AuthKey_XXX.p8")
-if err != nil {
-  log.Fatal("token error:", err)
-}
-
-token := &token.Token{
-  AuthKey: authKey,
-  // KeyID from developer account (Certificates, Identifiers & Profiles -> Keys)
-  KeyID:   "ABC123DEFG",
-  // TeamID from developer account (View Account -> Membership)
-  TeamID:  "DEF123GHIJ",
-}
-...
-
-client := apns2.NewTokenClient(token)
-res, err := client.Push(notification)
-```
-
-- You can use one APNs signing key to authenticate tokens for multiple apps.
-- A signing key works for both the development and production environments.
-- A signing key doesn’t expire but can be revoked.
-
-## Notification
-
-At a minimum, a _Notification_ needs a _DeviceToken_, a _Topic_ and a _Payload_.
-
-```go
-notification := &apns2.Notification{
-  DeviceToken: "11aa01229f15f0f0c52029d8cf8cd0aeaf2365fe4cebc4af26cd6d76b7919ef7",
-  Topic: "com.sideshow.Apns2",
-  Payload: []byte(`{"aps":{"alert":"Hello!"}}`),
-}
-```
-
-You can also set an optional _ApnsID_, _Expiration_ or _Priority_.
-
-```go
-notification.ApnsID =  "40636A2C-C093-493E-936A-2A4333C06DEA"
-notification.Expiration = time.Now()
-notification.Priority = apns2.PriorityLow
-```
-
-## Payload
-
-You can use raw bytes for the `notification.Payload` as above, or you can use the payload builder package which makes it easy to construct APNs payloads.
-
-```go
-// {"aps":{"alert":"hello","badge":1},"key":"val"}
-
-payload := payload.NewPayload().Alert("hello").Badge(1).Custom("key", "val")
-
-notification.Payload = payload
-client.Push(notification)
-```
-
-Refer to the [payload](https://godoc.org/github.com/sideshow/apns2/payload) docs for more info.
-
-## Response, Error handling
-
-APNS/2 draws the distinction between a valid response from Apple indicating whether or not the _Notification_ was sent or not, and an unrecoverable or unexpected _Error_;
-
-- An `Error` is returned if a non-recoverable error occurs, i.e. if there is a problem with the underlying _http.Client_ connection or _Certificate_, the payload was not sent, or a valid _Response_ was not received.
-- A `Response` is returned if the payload was successfully sent to Apple and a documented response was received. This struct will contain more information about whether or not the push notification succeeded, its _apns-id_ and if applicable, more information around why it did not succeed.
-
-To check if a `Notification` was successfully sent;
-
-```go
-res, err := client.Push(notification)
-if err != nil {
-  log.Println("There was an error", err)
-  return
-}
-
-if res.Sent() {
-  log.Println("Sent:", res.ApnsID)
-} else {
-  fmt.Printf("Not Sent: %v %v %v\n", res.StatusCode, res.ApnsID, res.Reason)
-}
-```
-
-## Context & Timeouts
-
-For better control over request cancellations and timeouts APNS/2 supports
-contexts. Using a context can be helpful if you want to cancel all pushes when
-the parent process is cancelled, or need finer grained control over individual
-push timeouts. See the [Google post](https://blog.golang.org/context) for more
-information on contexts.
-
-```go
-ctx, cancel = context.WithTimeout(context.Background(), 10 * time.Second)
-res, err := client.PushWithContext(ctx, notification)
-defer cancel()
-```
-
-## Speed & Performance
-
-Also see the wiki page on [APNS HTTP 2 Push Speed](https://github.com/sideshow/apns2/wiki/APNS-HTTP-2-Push-Speed).
-
-For best performance, you should hold on to an `apns2.Client` instance and not re-create it every push. The underlying TLS connection itself can take a few seconds to connect and negotiate, so if you are setting up an `apns2.Client` and tearing it down every push, then this will greatly affect performance. (Apple suggest keeping the connection open all the time).
-
-You should also limit the amount of `apns2.Client` instances. The underlying transport has a http connection pool itself, so a single client instance will be enough for most users (One instance can potentially do 4,000+ pushes per second). If you need more than this then one instance per CPU core is a good starting point.
-
-Speed is greatly affected by the location of your server and the quality of your network connection. If you're just testing locally, behind a proxy or if your server is outside USA then you're not going to get great performance. With a good server located in AWS, you should be able to get [decent throughput](https://github.com/sideshow/apns2/wiki/APNS-HTTP-2-Push-Speed).
-
-## Command line tool
-
-APNS/2 has a command line tool that can be installed with `go get github.com/sideshow/apns2/apns2`. Usage:
-
-```
-apns2 --help
-usage: apns2 --certificate-path=CERTIFICATE-PATH --topic=TOPIC [<flags>]
-
-Listens to STDIN to send notifications and writes APNS response code and reason to STDOUT.
-
-The expected format is: <DeviceToken> <APNS Payload>
-Example: aff0c63d9eaa63ad161bafee732d5bc2c31f66d552054718ff19ce314371e5d0 {"aps": {"alert": "hi"}}
-Flags:
-      --help               Show context-sensitive help (also try --help-long and --help-man).
-  -c, --certificate-path=CERTIFICATE-PATH
-                           Path to certificate file.
-  -t, --topic=TOPIC        The topic of the remote notification, which is typically the bundle ID for your app
-  -m, --mode="production"  APNS server to send notifications to. `production` or `development`. Defaults to `production`
-      --version            Show application version.

-This is a work-in-progress HTTP/2 implementation for Go.
-
-It will eventually live in the Go standard library and won't require
-any changes to your code to use.  It will just be automatic.
-
-Status:
-
-* The server support is pretty good. A few things are missing
-  but are being worked on.
-* The client work has just started but shares a lot of code
-  is coming along much quicker.
-
-Docs are at https://godoc.org/golang.org/x/net/http2
-
-Demo test server at https://http2.golang.org/
