+## 为什么使用 frp ？
 
-## frp 的作用
+通过在具有公网 IP 的节点上部署 frp 服务端，可以轻松地将内网服务穿透到公网，同时提供诸多专业的功能特性，这包括：
 
-* 利用处于内网或防火墙后的机器，对外网环境提供 http 或 https 服务。
-* 对于 http, https 服务支持基于域名的虚拟主机，支持自定义域名绑定，使多个域名可以共用一个80端口。
-* 利用处于内网或防火墙后的机器，对外网环境提供 tcp 和 udp 服务，例如在家里通过 ssh 访问处于公司内网环境内的主机。
+* 客户端服务端通信支持 TCP、KCP 以及 Websocket 等多种协议。
+* 采用 TCP 连接流式复用，在单个连接间承载更多请求，节省连接建立时间。
+* 代理组间的负载均衡。
+* 端口复用，多个服务通过同一个服务端端口暴露。
+* 多个原生支持的客户端插件（静态文件查看，HTTP、SOCK5 代理等），便于独立使用 frp 客户端完成某些工作。
+* 高度扩展性的服务端插件系统，方便结合自身需求进行功能扩展。
+* 服务端和客户端 UI 页面。
 
 ## 开发状态
 
-frp 仍然处于前期开发阶段，未经充分测试与验证，不推荐用于生产环境。
+frp 目前已被很多公司广泛用于测试、生产环境。
 
 master 分支用于发布稳定版本，dev 分支用于开发，您可以尝试下载最新的 release 版本进行测试。
 
-**目前的交互协议可能随时改变，不保证向后兼容，升级新版本时需要注意公告说明同时升级服务端和客户端。**
+我们正在进行 v2 大版本的开发，将会尝试在各个方面进行重构和升级，且不会与 v1 版本进行兼容，预计会持续一段时间。
 
-## 架构
+现在的 v0 版本将会在合适的时间切换为 v1 版本并且保证兼容性，后续只做 bug 修复和优化，不再进行大的功能性更新。
 
-![architecture](/doc/pic/architecture.png)
+## 文档
 
-## 使用示例
-
-根据对应的操作系统及架构，从 [Release](https://github.com/fatedier/frp/releases) 页面下载最新版本的程序。
-
-将 **frps** 及 **frps.ini** 放到具有公网 IP 的机器上。
-
-将 **frpc** 及 **frpc.ini** 放到处于内网环境的机器上。
-
-### 通过 ssh 访问公司内网机器
-
-1. 修改 frps.ini 文件，这里使用了最简化的配置：
-
-  ```ini
-  # frps.ini
-  [common]
-  bind_port = 7000
-  ```
-
-2. 启动 frps：
-
-  `./frps -c ./frps.ini`
-
-3. 修改 frpc.ini 文件，假设 frps 所在服务器的公网 IP 为 x.x.x.x；
-
-  ```ini
-  # frpc.ini
-  [common]
-  server_addr = x.x.x.x
-  server_port = 7000
-  
-  [ssh]
-  type = tcp
-  local_ip = 127.0.0.1
-  local_port = 22
-  remote_port = 6000
-  ```
-
-4. 启动 frpc：
-
-  `./frpc -c ./frpc.ini`
-
-5. 通过 ssh 访问内网机器，假设用户名为 test：
-
-  `ssh -oPort=6000 test@x.x.x.x`
-
-### 通过自定义域名访问部署于内网的 web 服务
-
-有时想要让其他人通过域名访问或者测试我们在本地搭建的 web 服务，但是由于本地机器没有公网 IP，无法将域名解析到本地的机器，通过 frp 就可以实现这一功能，以下示例为 http 服务，https 服务配置方法相同， vhost_http_port 替换为 vhost_https_port， type 设置为 https 即可。
-
-1. 修改 frps.ini 文件，设置 http 访问端口为 8080：
-
-  ```ini
-  # frps.ini
-  [common]
-  bind_port = 7000
-  vhost_http_port = 8080
-  ```
-
-2. 启动 frps；
-
-  `./frps -c ./frps.ini`
-
-3. 修改 frpc.ini 文件，假设 frps 所在的服务器的 IP 为 x.x.x.x，local_port 为本地机器上 web 服务对应的端口, 绑定自定义域名 `www.yourdomain.com`:
-
-  ```ini
-  # frpc.ini
-  [common]
-  server_addr = x.x.x.x
-  server_port = 7000
-
-  [web]
-  type = http
-  local_port = 80
-  custom_domains = www.yourdomain.com
-  ```
-
-4. 启动 frpc：
-
-  `./frpc -c ./frpc.ini`
-
-5. 将 `www.yourdomain.com` 的域名 A 记录解析到 IP `x.x.x.x`，如果服务器已经有对应的域名，也可以将 CNAME 记录解析到服务器原先的域名。
-
-6. 通过浏览器访问 `http://www.yourdomain.com:8080` 即可访问到处于内网机器上的 web 服务。
-
-### 转发 DNS 查询请求
-
-DNS 查询请求通常使用 UDP 协议，frp 支持对内网 UDP 服务的穿透，配置方式和 TCP 基本一致。
-
-1. 修改 frps.ini 文件：
-
-  ```ini
-  # frps.ini
-  [common]
-  bind_port = 7000
-  ```
-
-2. 启动 frps：
-
-  `./frps -c ./frps.ini`
-
-3. 修改 frpc.ini 文件，设置 frps 所在服务器的 IP 为 x.x.x.x，转发到 Google 的 DNS 查询服务器 `8.8.8.8` 的 udp 53 端口：
-
-  ```ini
-  # frpc.ini
-  [common]
-  server_addr = x.x.x.x
-  server_port = 7000
-  
-  [dns]
-  type = udp
-  local_ip = 8.8.8.8
-  local_port = 53
-  remote_port = 6000
-  ```
-
-4. 启动 frpc：
-
-  `./frpc -c ./frpc.ini`
-
-5. 通过 dig 测试 UDP 包转发是否成功，预期会返回 `www.google.com` 域名的解析结果：
-
-  `dig @x.x.x.x -p 6000 www.google.com`
-
-### 转发 Unix域套接字
-
-通过 tcp 端口访问内网的 unix域套接字(例如和 docker daemon 通信)。
-
-frps 的部署步骤同上。
-
-1. 启动 frpc，启用 `unix_domain_socket` 插件，配置如下：
-
-  ```ini
-  # frpc.ini
-  [common]
-  server_addr = x.x.x.x
-  server_port = 7000
-  
-  [unix_domain_socket]
-  type = tcp
-  remote_port = 6000
-  plugin = unix_domain_socket
-  plugin_unix_path = /var/run/docker.sock
-  ```
-
-2. 通过 curl 命令查看 docker 版本信息
-
-  `curl http://x.x.x.x:6000/version`
-
-### 对外提供简单的文件访问服务
-
-通过 `static_file` 插件可以对外提供一个简单的基于 HTTP 的文件访问服务。
-
-frps 的部署步骤同上。
-
-1. 启动 frpc，启用 `static_file` 插件，配置如下：
-
-  ```ini
-  # frpc.ini
-  [common]
-  server_addr = x.x.x.x
-  server_port = 7000
-
-  [test_static_file]
-  type = tcp
-  remote_port = 6000
-  plugin = static_file
-  # 要对外暴露的文件目录
-  plugin_local_path = /tmp/file
-  # 访问 url 中会被去除的前缀，保留的内容即为要访问的文件路径
-  plugin_strip_prefix = static
-  plugin_http_user = abc
-  plugin_http_passwd = abc
-  ```
-
-2. 通过浏览器访问 `http://x.x.x.x:6000/static/` 来查看位于 `/tmp/file` 目录下的文件，会要求输入已设置好的用户名和密码。
-
-### 安全地暴露内网服务
-
-对于某些服务来说如果直接暴露于公网上将会存在安全隐患。
-
-使用 **stcp(secret tcp)** 类型的代理可以避免让任何人都能访问到要穿透的服务，但是访问者也需要运行另外一个 frpc。
-
-以下示例将会创建一个只有自己能访问到的 ssh 服务代理。
-
-frps 的部署步骤同上。
-
-1. 启动 frpc，转发内网的 ssh 服务，配置如下，不需要指定远程端口：
-
-  ```ini
-  # frpc.ini
-  [common]
-  server_addr = x.x.x.x
-  server_port = 7000
-
-  [secret_ssh]
-  type = stcp
-  # 只有 sk 一致的用户才能访问到此服务
-  sk = abcdefg
-  local_ip = 127.0.0.1
-  local_port = 22
-  ```
-
-2. 在要访问这个服务的机器上启动另外一个 frpc，配置如下：
-
-  ```ini
-  # frpc.ini
-  [common]
-  server_addr = x.x.x.x
-  server_port = 7000
-
-  [secret_ssh_visitor]
-  type = stcp
-  # stcp 的访问者
-  role = visitor
-  # 要访问的 stcp 代理的名字
-  server_name = secret_ssh
-  sk = abcdefg
-  # 绑定本地端口用于访问 ssh 服务
-  bind_addr = 127.0.0.1
-  bind_port = 6000
-  ```
-
-3. 通过 ssh 访问内网机器，假设用户名为 test：
-
-  `ssh -oPort=6000 test@127.0.0.1`
-
-### 点对点内网穿透
-
-frp 提供了一种新的代理类型 **xtcp** 用于应对在希望传输大量数据且流量不经过服务器的场景。
-
-使用方式同 **stcp** 类似，需要在两边都部署上 frpc 用于建立直接的连接。
-
-目前处于开发的初级阶段，并不能穿透所有类型的 NAT 设备，所以穿透成功率较低。穿透失败时可以尝试 **stcp** 的方式。
-
-1. frps 除正常配置外需要额外配置一个 udp 端口用于支持该类型的客户端:
-
-  ```ini
-  bind_udp_port = 7001
-  ```
-
-2. 启动 frpc，转发内网的 ssh 服务，配置如下，不需要指定远程端口:
-
-  ```ini
-  # frpc.ini
-  [common]
-  server_addr = x.x.x.x
-  server_port = 7000
-
-  [p2p_ssh]
-  type = xtcp
-  # 只有 sk 一致的用户才能访问到此服务
-  sk = abcdefg
-  local_ip = 127.0.0.1
-  local_port = 22
-  ```
-
-3. 在要访问这个服务的机器上启动另外一个 frpc，配置如下:
-
-  ```ini
-  # frpc.ini
-  [common]
-  server_addr = x.x.x.x
-  server_port = 7000
-
-  [p2p_ssh_visitor]
-  type = xtcp
-  # xtcp 的访问者
-  role = visitor
-  # 要访问的 xtcp 代理的名字
-  server_name = p2p_ssh
-  sk = abcdefg
-  # 绑定本地端口用于访问 ssh 服务
-  bind_addr = 127.0.0.1
-  bind_port = 6000
-  ```
-
-4. 通过 ssh 访问内网机器，假设用户名为 test:
-
-  `ssh -oPort=6000 test@127.0.0.1`
-
-### 通过 frpc 所在机器访问外网
-
-frpc 内置了 http proxy 和 socks5 插件，可以使其他机器通过 frpc 的网络访问互联网。
-
-frps 的部署步骤同上。
-
-1. 启动 frpc，启用 http_proxy 或 socks5 插件(plugin 换为 socks5 即可)， 配置如下：
-
-  ```ini
-  # frpc.ini
-  [common]
-  server_addr = x.x.x.x
-  server_port = 7000
-  
-  [http_proxy]
-  type = tcp
-  remote_port = 6000
-  plugin = http_proxy
-  ```
-
-2. 浏览器设置 http 或 socks5 代理地址为 `x.x.x.x:6000`，通过 frpc 机器的网络访问互联网。
-
-## 功能说明
-
-### 配置文件
-
-由于 frp 目前支持的功能和配置项较多，未在文档中列出的功能可以从完整的示例配置文件中发现。
-
-[frps 完整配置文件](./conf/frps_full.ini)
-
-[frpc 完整配置文件](./conf/frpc_full.ini)
-
-### Dashboard
-
-通过浏览器查看 frp 的状态以及代理统计信息展示。
-
-需要在 frps.ini 中指定 dashboard 服务使用的端口，即可开启此功能：
-
-```ini
-[common]
-dashboard_port = 7500
-# dashboard 用户名密码，默认都为 admin
-dashboard_user = admin
-dashboard_pwd = admin
-```
-
-打开浏览器通过 `http://[server_addr]:7500` 访问 dashboard 界面，用户名密码默认为 `admin`。
-
-![dashboard](/doc/pic/dashboard.png)
-
-### 身份验证
-
-从 v0.10.0 版本开始，所有 proxy 配置全部放在客户端(也就是之前版本的特权模式)，服务端和客户端的 common 配置中的 `privilege_token` 参数一致则身份验证通过。
-
-需要注意的是 frpc 所在机器和 frps 所在机器的时间相差不能超过 15 分钟，因为时间戳会被用于加密验证中，防止报文被劫持后被其他人利用。
-
-这个超时时间可以在配置文件中通过 `authentication_timeout` 这个参数来修改，单位为秒，默认值为 900，即 15 分钟。如果修改为 0，则 frps 将不对身份验证报文的时间戳进行超时校验。
-
-### 加密与压缩
-
-这两个功能默认是不开启的，需要在 frpc.ini 中通过配置来为指定的代理启用加密与压缩的功能，压缩算法使用 snappy：
-
-```ini
-# frpc.ini
-[ssh]
-type = tcp
-local_port = 22
-remote_port = 6000
-use_encryption = true
-use_compression = true
-```
-
-如果公司内网防火墙对外网访问进行了流量识别与屏蔽，例如禁止了 ssh 协议等，通过设置 `use_encryption = true`，将 frpc 与 frps 之间的通信内容加密传输，将会有效防止流量被拦截。
-
-如果传输的报文长度较长，通过设置 `use_compression = true` 对传输内容进行压缩，可以有效减小 frpc 与 frps 之间的网络流量，加快流量转发速度，但是会额外消耗一些 cpu 资源。
-
-### 客户端热加载配置文件
-
-当修改了 frpc 中的代理配置，可以通过 `frpc reload` 命令来动态加载配置文件，通常会在 10 秒内完成代理的更新。
-
-启用此功能需要在 frpc 中启用 admin 端口，用于提供 API 服务。配置如下：
-
-```ini
-# frpc.ini
-[common]
-admin_addr = 127.0.0.1
-admin_port = 7400
-```
-
-之后执行重启命令：
-
-`frpc reload -c ./frpc.ini`
-
-等待一段时间后客户端会根据新的配置文件创建、更新、删除代理。
-
-**需要注意的是，[common] 中的参数除了 start 外目前无法被修改。**
-
-### 客户端查看代理状态
-
-frpc 支持通过 `frpc status -c ./frpc.ini` 命令查看代理的状态信息，此功能需要在 frpc 中配置 admin 端口。
-
-### 特权模式
-
-由于从 v0.10.0 版本开始，所有 proxy 都在客户端配置，原先的特权模式是目前唯一支持的模式。
-
-#### 端口白名单
-
-为了防止端口被滥用，可以手动指定允许哪些端口被使用，在 frps.ini 中通过 privilege_allow_ports 来指定：
-
-```ini
-# frps.ini
-[common]
-privilege_allow_ports = 2000-3000,3001,3003,4000-50000
-```
-
-privilege_allow_ports 可以配置允许使用的某个指定端口或者是一个范围内的所有端口，以 `,` 分隔，指定的范围以 `-` 分隔。
-
-### TCP 多路复用
-
-从 v0.10.0 版本开始，客户端和服务器端之间的连接支持多路复用，不再需要为每一个用户请求创建一个连接，使连接建立的延迟降低，并且避免了大量文件描述符的占用，使 frp 可以承载更高的并发数。
-
-该功能默认启用，如需关闭，可以在 frps.ini 和 frpc.ini 中配置，该配置项在服务端和客户端必须一致：
-
-```ini
-# frps.ini 和 frpc.ini 中
-[common]
-tcp_mux = false
-```
-
-### 底层通信可选 kcp 协议
-
-从 v0.12.0 版本开始，底层通信协议支持选择 kcp 协议，在弱网环境下传输效率提升明显，但是会有一些额外的流量消耗。
-
-开启 kcp 协议支持：
-
-1. 在 frps.ini 中启用 kcp 协议支持，指定一个 udp 端口用于接收客户端请求：
-
-  ```ini
-  # frps.ini
-  [common]
-  bind_port = 7000
-  # kcp 绑定的是 udp 端口，可以和 bind_port 一样
-  kcp_bind_port = 7000
-  ```
-
-2. 在 frpc.ini 指定需要使用的协议类型，目前只支持 tcp 和 kcp。其他代理配置不需要变更：
-
-  ```ini
-  # frpc.ini
-  [common]
-  server_addr = x.x.x.x
-  # server_port 指定为 frps 的 kcp_bind_port
-  server_port = 7000
-  protocol = kcp
-  ```
-
-3. 像之前一样使用 frp，需要注意开放相关机器上的 udp 的端口的访问权限。
-
-### 连接池
-
-默认情况下，当用户请求建立连接后，frps 才会请求 frpc 主动与后端服务建立一个连接。当为指定的代理启用连接池后，frp 会预先和后端服务建立起指定数量的连接，每次接收到用户请求后，会从连接池中取出一个连接和用户连接关联起来，避免了等待与后端服务建立连接以及 frpc 和 frps 之间传递控制信息的时间。
-
-这一功能比较适合有大量短连接请求时开启。
-
-1. 首先可以在 frps.ini 中设置每个代理可以创建的连接池上限，避免大量资源占用，客户端设置超过此配置后会被调整到当前值：
-
-  ```ini
-  # frps.ini
-  [common]
-  max_pool_count = 5
-  ```
-
-2. 在 frpc.ini 中为客户端启用连接池，指定预创建连接的数量：
-
-  ```ini
-  # frpc.ini
-  [common]
-  pool_count = 1
-  ```
-
-### 修改 Host Header
-
-通常情况下 frp 不会修改转发的任何数据。但有一些后端服务会根据 http 请求 header 中的 host 字段来展现不同的网站，例如 nginx 的虚拟主机服务，启用 host-header 的修改功能可以动态修改 http 请求中的 host 字段。该功能仅限于 http 类型的代理。
-
-```ini
-# frpc.ini
-[web]
-type = http
-local_port = 80
-custom_domains = test.yourdomain.com
-host_header_rewrite = dev.yourdomain.com
-```
-
-原来 http 请求中的 host 字段 `test.yourdomain.com` 转发到后端服务时会被替换为 `dev.yourdomain.com`。
-
-### 获取用户真实 IP
-
-目前只有 **http** 类型的代理支持这一功能，可以通过用户请求的 header 中的 `X-Forwarded-For` 和 `X-Real-IP` 来获取用户真实 IP。
-
-**需要注意的是，目前只在每一个用户连接的第一个 HTTP 请求中添加了这两个 header。**
-
-### 通过密码保护你的 web 服务
-
-由于所有客户端共用一个 frps 的 http 服务端口，任何知道你的域名和 url 的人都能访问到你部署在内网的 web 服务，但是在某些场景下需要确保只有限定的用户才能访问。
-
-frp 支持通过 HTTP Basic Auth 来保护你的 web 服务，使用户需要通过用户名和密码才能访问到你的服务。
-
-该功能目前仅限于 http 类型的代理，需要在 frpc 的代理配置中添加用户名和密码的设置。
-
-```ini
-# frpc.ini
-[web]
-type = http
-local_port = 80
-custom_domains = test.yourdomain.com
-http_user = abc
-http_pwd = abc
-```
-
-通过浏览器访问 `http://test.yourdomain.com`，需要输入配置的用户名和密码才能访问。
-
-### 自定义二级域名
-
-在多人同时使用一个 frps 时，通过自定义二级域名的方式来使用会更加方便。
-
-通过在 frps 的配置文件中配置 `subdomain_host`，就可以启用该特性。之后在 frpc 的 http、https 类型的代理中可以不配置 `custom_domains`，而是配置一个 `subdomain` 参数。
-
-只需要将 `*.{subdomain_host}` 解析到 frps 所在服务器。之后用户可以通过 `subdomain` 自行指定自己的 web 服务所需要使用的二级域名，通过 `{subdomain}.{subdomain_host}` 来访问自己的 web 服务。
-
-```ini
-# frps.ini
-[common]
-subdomain_host = frps.com
-```
-
-将泛域名 `*.frps.com` 解析到 frps 所在服务器的 IP 地址。
-
-```ini
-# frpc.ini
-[web]
-type = http
-local_port = 80
-subdomain = test
-```
-
-frps 和 fprc 都启动成功后，通过 `test.frps.com` 就可以访问到内网的 web 服务。
-
-需要注意的是如果 frps 配置了 `subdomain_host`，则 `custom_domains` 中不能是属于 `subdomain_host` 的子域名或者泛域名。
-
-同一个 http 或 https 类型的代理中 `custom_domains`  和 `subdomain` 可以同时配置。
-
-### URL 路由
-
-frp 支持根据请求的 URL 路径路由转发到不同的后端服务。
-
-通过配置文件中的 `locations` 字段指定一个或多个 proxy 能够匹配的 URL 前缀(目前仅支持最大前缀匹配，之后会考虑正则匹配)。例如指定 `locations = /news`，则所有 URL 以 `/news` 开头的请求都会被转发到这个服务。
-
-```ini
-# frpc.ini
-[web01]
-type = http
-local_port = 80
-custom_domains = web.yourdomain.com
-locations = /
-
-[web02]
-type = http
-local_port = 81
-custom_domains = web.yourdomain.com
-locations = /news,/about
-```
-
-按照上述的示例配置后，`web.yourdomain.com` 这个域名下所有以 `/news` 以及 `/about` 作为前缀的 URL 请求都会被转发到 web02，其余的请求会被转发到 web01。
-
-### 通过代理连接 frps
-
-在只能通过代理访问外网的环境内，frpc 支持通过 HTTP PROXY 和 frps 进行通信。
-
-可以通过设置 `HTTP_PROXY` 系统环境变量或者通过在 frpc 的配置文件中设置 `http_proxy` 参数来使用此功能。
-
-仅在 `protocol = tcp` 时生效。
-
-```ini
-# frpc.ini
-[common]
-server_addr = x.x.x.x
-server_port = 7000
-http_proxy = http://user:pwd@192.168.1.128:8080
-```
-
-### 范围端口映射
-
-在 frpc 的配置文件中可以指定映射多个端口，目前只支持 tcp 和 udp 的类型。
-
-这一功能通过 `range:` 段落标记来实现，客户端会解析这个标记中的配置，将其拆分成多个 proxy，每一个 proxy 以数字为后缀命名。
-
-例如要映射本地 6000-6005, 6007 这6个端口，主要配置如下：
-
-```ini
-# frpc.ini
-[range:test_tcp]
-type = tcp
-local_ip = 127.0.0.1
-local_port = 6000-6006,6007
-remote_port = 6000-6006,6007
-```
-
-实际连接成功后会创建 6 个 proxy，命名为 `test_tcp_0, test_tcp_1 ... test_tcp_5`。
-
-### 插件
-
-默认情况下，frpc 只会转发请求到本地 tcp 或 udp 端口。
-
-插件模式是为了在客户端提供更加丰富的功能，目前内置的插件有 `unix_domain_socket`、`http_proxy`、`socks5`、`static_file`。具体使用方式请查看[使用示例](#使用示例)。
-
-通过 `plugin` 指定需要使用的插件，插件的配置参数都以 `plugin_` 开头。使用插件后 `local_ip` 和 `local_port` 不再需要配置。
-
-使用 **http_proxy** 插件的示例:
-
-```ini
-# frpc.ini
-[http_proxy]
-type = tcp
-remote_port = 6000
-plugin = http_proxy
-plugin_http_user = abc
-plugin_http_passwd = abc
-```
-
-`plugin_http_user` 和 `plugin_http_passwd` 即为 `http_proxy` 插件可选的配置参数。
-

-# Quick Start
-
-frp is easier to use compared with other similar projects.
-
-We will use two simple demo to demonstrate how to use frp.
-
-1. How to create a connection to **server A**'s **ssh port** by **server B** with **public IP address** x.x.x.x(replace to the real IP address of your server).
-2. How to visit web service in **server A**'s **8000 port** and **8001 port** by **web01.yourdomain.com** and **web02.yourdomain.com** through **server B** with public ID address.
-
-### Download SourceCode
-
-`go get github.com/fatedier/frp` is recommended, then the code will be copied to the directory `$GOPATH/src/github.com/fatedier/frp`.
-
-Or you can use `git clone https://github.com/fatedier/frp.git $GOPATH/src/github.com/fatedier/frp`.
-
-If you want to try it quickly, download the compiled program and configuration files from [https://github.com/fatedier/frp/releases](https://github.com/fatedier/frp/releases).
-
-### Compile
-
-Enter the root directory and execute `make`, then wait until finished.
-
-**bin** include all executable programs when **conf** include corresponding configuration files.
-
-### Pre-requirement
-
-* Go environment. Version of go >= 1.4.
-* Godep (if not exist, `go get` will be executed to download godep when compiling)
-
-### Deploy
-
-1. Move `./bin/frps` and `./conf/frps.ini` to any directory of **server B**.
-2. Move `./bin/frpc` and `./conf/frpc.ini` to any directory of **server A**.
-3. Modify all configuration files, details in next paragraph.
-4. Execute `nohup ./frps &` or `nohup ./frps -c ./frps.ini &` in **server B**.
-5. Execute `nohup ./frpc &` or `nohup ./frpc -c ./frpc.ini &` in **server A**.
-6. Use `ssh -oPort=6000 {user}@x.x.x.x` to test if frp is work(replace {user} to real username in **server A**), or visit custom domains by browser.

-## Http port forwarding and Custom domains binding
-
-If you only want to forward port one by one, you just need refer to [Tcp port forwarding](/doc/quick_start_en.md#Tcp-port-forwarding).If you want to visit different web pages deployed in different web servers by **server B**'s **80 port**, you should specify the type as **http**.
-
-You also need to resolve your **A record** of your custom domain to [server_addr], or resolve your **CNAME record** to [server_addr] if [server_addr] is a domain.
-
-After that, you can visit your web pages in local server by custom domains.

-# frp 使用文档
-
-相比于其他项目而言 frp 更易于部署和使用，这里我们用两个简单的示例来演示 frp 的使用过程。
-
-1. 如何通过一台拥有公网IP地址的**服务器B**，访问处于公司内部网络环境中的**服务器A**的**ssh**端口，**服务器B**的IP地址为 x.x.x.x（测试时替换为真实的IP地址）。
-2. 如何利用一台拥有公网IP地址的**服务器B**，使通过 **web01.yourdomain.com** 可以访问内网环境中**服务器A**上**8000端口**的web服务，**web02.yourdomain.com** 可以访问**服务器A**上**8001端口**的web服务。
-
-### 下载源码
-
-推荐直接使用 `go get github.com/fatedier/frp` 下载源代码安装，执行命令后代码将会拷贝到 `$GOPATH/src/github.com/fatedier/frp` 目录下。
-
-或者可以使用 `git clone https://github.com/fatedier/frp.git $GOPATH/src/github.com/fatedier/frp` 拷贝到相应目录下。
-
-如果您想快速进行测试，也可以根据您服务器的操作系统及架构直接下载编译好的程序及示例配置文件，[https://github.com/fatedier/frp/releases](https://github.com/fatedier/frp/releases)。
-
-### 编译
-
-进入下载后的源码根目录，执行 `make` 命令，等待编译完成。
-
-编译完成后， **bin** 目录下是编译好的可执行文件，**conf** 目录下是示例配置文件。
-
-### 依赖
-
-* go 1.4 以上版本
-* godep （如果检查不存在，编译时会通过 `go get` 命令安装）
-
-### 部署
-
-1. 将 ./bin/frps 和 ./conf/frps.ini 拷贝至**服务器B**任意目录。
-2. 将 ./bin/frpc 和 ./conf/frpc.ini 拷贝至**服务器A**任意目录。
-3. 根据要实现的功能修改两边的配置文件，详细内容见后续章节说明。
-4. 在服务器B执行 `nohup ./frps &` 或者 `nohup ./frps -c ./frps.ini &`。
-5. 在服务器A执行 `nohup ./frpc &` 或者 `nohup ./frpc -c ./frpc.ini &`。
-6. 通过 `ssh -oPort=6000 {user}@x.x.x.x` 测试是否能够成功连接**服务器A**（{user}替换为**服务器A**上存在的真实用户），或通过浏览器访问自定义域名验证 http 服务是否转发成功。
-
-## tcp 端口转发
-
-转发 tcp 端口需要按照需求修改 frps 和 frpc 的配置文件。
-
-### 配置文件
-
-#### frps.ini
-
-```ini
-[common]
-bind_addr = 0.0.0.0
-# 用于接收 frpc 连接的端口
-bind_port = 7000
-log_file = ./frps.log
-log_level = info
-
-# ssh 为代理的自定义名称，可以有多个，不能重复，和frpc中名称对应
-[ssh]
-auth_token = 123 
-bind_addr = 0.0.0.0
-# 最后将通过此端口访问后端服务
-listen_port = 6000
-```
-
-#### frpc.ini
-
-```ini
-[common]
-# frps 所在服务器绑定的IP地址
-server_addr = x.x.x.x
-server_port = 7000
-log_file = ./frpc.log
-log_level = info
-# 用于身份验证
-auth_token = 123 
-
-# ssh 需要和 frps.ini 中配置一致
-[ssh]
-# 需要转发的本地端口
-local_port = 22
-# 启用加密，frpc与frps之间通信加密，默认为 false
-use_encryption = true
-```
-
-## http 端口转发，自定义域名绑定
-
-如果只需要一对一的转发，例如**服务器B**的**80端口**转发**服务器A**的**8000端口**，则只需要配置 [tcp 端口转发](/doc/quick_start_zh.md#tcp-端口转发) 即可，如果需要使**服务器B**的**80端口**可以转发至**多个**web服务端口，则需要指定代理的类型为 http，并且在 frps 的配置文件中配置用于提供 http 转发服务的端口。
-
-按照如下的内容修改配置文件后，需要将自定义域名的 **A 记录**解析到 [server_addr]，如果 [server_addr] 是域名也可以将自定义域名的 **CNAME 记录**解析到 [server_addr]。
-
-之后就可以通过自定义域名访问到本地的多个 web 服务。
-
-### 配置文件
-
-#### frps.ini
-
-```ini
-[common]
-bind_addr = 0.0.0.0
-bind_port = 7000
-# 如果需要支持http类型的代理则需要指定一个端口
-vhost_http_port = 80
-log_file = ./frps.log
-log_level = info
-
-[web01]
-# type 默认为 tcp，这里需要特别指定为 http
-type = http
-auth_token = 123
-# 自定义域名绑定，如果需要同时绑定多个以英文逗号分隔
-custom_domains = web01.yourdomain.com
-
-[web02]
-type = http
-auth_token = 123
-custom_domains = web02.yourdomain.com
-```
-
-#### frpc.ini
-
-```ini
-[common]
-server_addr = x.x.x.x
-server_port = 7000
-log_file = ./frpc.log
-log_level = info

+### Server Plugin
+
+frp server plugin is aimed to extend frp's ability without modifying the Golang code.
+
+An external server should run in a different process receiving RPC calls from frps.
+Before frps is doing some operations, it will send RPC requests to notify the external RPC server and act according to its response.
+
+### RPC request
+
+RPC requests are based on JSON over HTTP.
+
+When a server plugin accepts an operation request, it can respond with three different responses:
+
+* Reject operation and return a reason.
+* Allow operation and keep original content.
+* Allow operation and return modified content.
+
+### Interface
+
+HTTP path can be configured for each manage plugin in frps. We'll assume for this example that it's `/handler`.
+
+A request to the RPC server will look like:
+
+```
+POST /handler?version=0.1.0&op=Login
+{
+    "version": "0.1.0",
+    "op": "Login",
+    "content": {
+        ... // Operation info
+    }
+}
+
+Request Header:
+X-Frp-Reqid: for tracing
+```
+
+The response can look like any of the following:
+
+* Non-200 HTTP response status code (this will automatically tell frps that the request should fail)
+
+* Reject operation:
+
+```
+{
+    "reject": true,
+    "reject_reason": "invalid user"
+}
+```
+
+* Allow operation and keep original content:
+
+```
+{
+    "reject": false,
+    "unchange": true
+}
+```
+
+* Allow operation and modify content
+
+```
+{
+    "unchange": "false",
+    "content": {
+        ... // Replaced content
+    }
+}
+```
+
+### Operation
+
+Currently `Login`, `NewProxy`, `CloseProxy`, `Ping`, `NewWorkConn` and `NewUserConn` operations are supported.
+
+#### Login
+
+Client login operation
+
+```

+
+#### CloseProxy
+
+A previously created proxy is closed.
+
+Please note that one request will be sent for every proxy that is closed, do **NOT** use this
+if you have too many proxies bound to a single client, as this may exhaust the server's resources.
+
+```
+{
+    "content": {
+        "user": {
+            "user": <string>,

+
+### Server Plugin Configuration
+
+```ini
+# frps.ini
+[common]
+bind_port = 7000
+
+[plugin.user-manager]
+addr = 127.0.0.1:9000
+path = /handler
+ops = Login
+
+[plugin.port-manager]
+addr = 127.0.0.1:9001
+path = /handler
+ops = NewProxy
+```
+
+- addr: the address where the external RPC service listens. Defaults to http. For https, specify the schema: `addr = https://127.0.0.1:9001`.
+- path: http request url path for the POST request.
+- ops: operations plugin needs to handle (e.g. "Login", "NewProxy", ...).
+- tls_verify: When the schema is https, we verify by default. Set this value to false if you want to skip verification.
+
+### Metadata
+
+Metadata will be sent to the server plugin in each RPC request.
+
+There are 2 types of metadata entries - 1 under `[common]` and the other under each proxy configuration.
+Metadata entries under `[common]` will be sent in `Login` under the key `metas`, and in any other RPC request under `user.metas`.
+Metadata entries under each proxy configuration will be sent in `NewProxy` op only, under `metas`.
+
+Metadata entries start with `meta_`. This is an example of metadata entries in `[common]` and under the proxy named `[ssh]`:
+
+```
+# frpc.ini
+[common]
+server_addr = 127.0.0.1
+server_port = 7000
+user = fake
+meta_token = fake
+meta_version = 1.0.0
+
+[ssh]
+type = tcp
+local_port = 22
+remote_port = 6000
+meta_id = 123
+```
