 * Direct reverse proxy, like haproxy.
 * Load balance to different service in frpc.

-[![GoDoc](https://godoc.org/github.com/docopt/docopt.go?status.png)](https://godoc.org/github.com/docopt/docopt.go)
-
-An implementation of [docopt](http://docopt.org/) in the
-[Go](http://golang.org/) programming language.
-
-**docopt** helps you create *beautiful* command-line interfaces easily:
-
-```go
-package main
-
-import (
-	"fmt"
-	"github.com/docopt/docopt-go"
-)
-
-func main() {
-	  usage := `Naval Fate.
-
-Usage:
-  naval_fate ship new <name>...
-  naval_fate ship <name> move <x> <y> [--speed=<kn>]
-  naval_fate ship shoot <x> <y>
-  naval_fate mine (set|remove) <x> <y> [--moored|--drifting]
-  naval_fate -h | --help
-  naval_fate --version
-
-Options:
-  -h --help     Show this screen.
-  --version     Show version.
-  --speed=<kn>  Speed in knots [default: 10].
-  --moored      Moored (anchored) mine.
-  --drifting    Drifting mine.`
-
-	  arguments, _ := docopt.Parse(usage, nil, true, "Naval Fate 2.0", false)
-	  fmt.Println(arguments)
-}
-```
-
-**docopt** parses command-line arguments based on a help message. Don't
-write parser code: a good help message already has all the necessary
-information in it.
-
-## Installation
-
-⚠ Use the alias “docopt-go”. To use docopt in your Go code:
-
-```go
-import "github.com/docopt/docopt-go"
-```
-
-To install docopt according to your `$GOPATH`:
-
-```console
-$ go get github.com/docopt/docopt-go
-```
-
-## API
-
-```go
-func Parse(doc string, argv []string, help bool, version string,
-    optionsFirst bool, exit ...bool) (map[string]interface{}, error)
-```
-Parse `argv` based on the command-line interface described in `doc`.
-
-Given a conventional command-line help message, docopt creates a parser and
-processes the arguments. See
-https://github.com/docopt/docopt#help-message-format for a description of the
-help message format. If `argv` is `nil`, `os.Args[1:]` is used.
-
-docopt returns a map of option names to the values parsed from `argv`, and an
-error or `nil`.
-
-More documentation for docopt is available at
-[GoDoc.org](https://godoc.org/github.com/docopt/docopt.go).
-
-## Testing
-
-All tests from the Python version are implemented and passing
-at [Travis CI](https://travis-ci.org/docopt/docopt.go). New
-language-agnostic tests have been added
-to [test_golang.docopt](test_golang.docopt).
-
-To run tests for docopt-go, use `go test`.

+# Gorilla WebSocket
+
+Gorilla WebSocket is a [Go](http://golang.org/) implementation of the
+[WebSocket](http://www.rfc-editor.org/rfc/rfc6455.txt) protocol.
+
+[![Build Status](https://travis-ci.org/gorilla/websocket.svg?branch=master)](https://travis-ci.org/gorilla/websocket)
+[![GoDoc](https://godoc.org/github.com/gorilla/websocket?status.svg)](https://godoc.org/github.com/gorilla/websocket)
+
+### Documentation
+
+* [API Reference](http://godoc.org/github.com/gorilla/websocket)
+* [Chat example](https://github.com/gorilla/websocket/tree/master/examples/chat)
+* [Command example](https://github.com/gorilla/websocket/tree/master/examples/command)
+* [Client and server example](https://github.com/gorilla/websocket/tree/master/examples/echo)
+* [File watch example](https://github.com/gorilla/websocket/tree/master/examples/filewatch)
+
+### Status
+
+The Gorilla WebSocket package provides a complete and tested implementation of
+the [WebSocket](http://www.rfc-editor.org/rfc/rfc6455.txt) protocol. The
+package API is stable.
+
+### Installation
+
+    go get github.com/gorilla/websocket
+
+### Protocol Compliance
+
+The Gorilla WebSocket package passes the server tests in the [Autobahn Test
+Suite](http://autobahn.ws/testsuite) using the application in the [examples/autobahn
+subdirectory](https://github.com/gorilla/websocket/tree/master/examples/autobahn).

+1. Large messages are fragmented in [Chrome's new WebSocket implementation](http://www.ietf.org/mail-archive/web/hybi/current/msg10503.html).
+2. The application can get the type of a received data message by implementing
+   a [Codec marshal](http://godoc.org/golang.org/x/net/websocket#Codec.Marshal)
+   function.
+3. The go.net io.Reader and io.Writer operate across WebSocket frame boundaries.
+  Read returns when the input buffer is full or a frame boundary is
+  encountered. Each call to Write sends a single frame message. The Gorilla
+  io.Reader and io.WriteCloser operate on a single WebSocket message.
