-### Monitor
-
-When dashboard is enabled, frps will save monitor data in cache. It will be cleared after process restart.
-
-Prometheus is also supported.
-
-#### Prometheus
-
-Enable dashboard first, then configure `enable_prometheus = true` in `frps.ini`.
-
-`http://{dashboard_addr}/metrics` will provide prometheus monitor data.
-
 ### Authenticating the Client
 
-There are 2 authentication methods to authenticate frpc with frps. 
-
-You can decide which one to use by configuring `authentication_method` under `[common]` in `frpc.ini` and `frps.ini`.
-
-Configuring `authenticate_heartbeats = true` under `[common]` will use the configured authentication method to add and validate authentication on every heartbeat between frpc and frps.
-
-Configuring `authenticate_new_work_conns = true` under `[common]` will do the same for every new work connection between frpc and frps.
-
-#### Token Authentication
-
-When specifying `authentication_method = token` under `[common]` in `frpc.ini` and `frps.ini` - token based authentication will be used.
-
-Make sure to specify the same `token` in the `[common]` section in `frps.ini` and `frpc.ini` for frpc to pass frps validation
-
-#### OIDC Authentication
-
-When specifying `authentication_method = oidc` under `[common]` in `frpc.ini` and `frps.ini` - OIDC based authentication will be used.
-
-OIDC stands for OpenID Connect, and the flow used is called [Client Credentials Grant](https://tools.ietf.org/html/rfc6749#section-4.4).
-
-To use this authentication type - configure `frpc.ini` and `frps.ini` as follows:
-
-```ini
-# frps.ini
-[common]
-authentication_method = oidc
-oidc_issuer = https://example-oidc-issuer.com/
-oidc_audience = https://oidc-audience.com/.default
-```
-
-```ini
-# frpc.ini
-[common]
-authentication_method = oidc
-oidc_client_id = 98692467-37de-409a-9fac-bb2585826f18 # Replace with OIDC client ID
-oidc_client_secret = oidc_secret
-oidc_audience = https://oidc-audience.com/.default
-oidc_token_endpoint_url = https://example-oidc-endpoint.com/oauth2/v2.0/token

+## 架构
+
+![architecture](/doc/pic/architecture.png)
+
+## 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。
+
+### 为本地 HTTP 服务启用 HTTPS
+
+通过 `https2http` 插件可以让本地 HTTP 服务转换成 HTTPS 服务对外提供。
+
+1. 启用 frpc，启用 `https2http` 插件，配置如下:
+
+  ```ini
+  # frpc.ini
+  [common]
+  server_addr = x.x.x.x
+  server_port = 7000
+
+  [test_htts2http]
+  type = https
+  custom_domains = test.yourdomain.com
+
+  plugin = https2http
+  plugin_local_addr = 127.0.0.1:80
+
+  # HTTPS 证书相关的配置
+  plugin_crt_path = ./server.crt
+  plugin_key_path = ./server.key
+  plugin_host_header_rewrite = 127.0.0.1
+  plugin_header_X-From-Where = frp
+  ```
+
+2. 通过浏览器访问 `https://test.yourdomain.com` 即可。
+
+### 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

+  ```
+
+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`
+
+## 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)
+
+### 配置文件模版渲染
+
+配置文件支持使用系统环境变量进行模版渲染，模版格式采用 Go 的标准格式。
+
+示例配置如下:
+
+```ini
+# frpc.ini
+[common]
+server_addr = {{ .Envs.FRP_SERVER_ADDR }}
+server_port = 7000
+
+[ssh]
+type = tcp
+local_ip = 127.0.0.1
+local_port = 22
+remote_port = {{ .Envs.FRP_SSH_REMOTE_PORT }}
+```
+
+启动 frpc 程序:
+
+```
+export FRP_SERVER_ADDR="x.x.x.x"
+export FRP_SSH_REMOTE_PORT="6000"
+./frpc -c ./frpc.ini
+```
+
+frpc 会自动使用环境变量渲染配置文件模版，所有环境变量需要以 `.Envs` 为前缀。
+
+### Dashboard
+
+通过浏览器查看 frp 的状态以及代理统计信息展示。
+
+**注：Dashboard 尚未针对大量的 proxy 数据展示做优化，如果出现 Dashboard 访问较慢的情况，请不要启用此功能。**
+
+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)
+
+### Admin UI
+
+Admin UI 可以帮助用户通过浏览器来查询和管理客户端的 proxy 状态和配置。
+
+需要在 frpc.ini 中指定 admin 服务使用的端口，即可开启此功能：
+
+```ini
+[common]
+admin_addr = 127.0.0.1
+admin_port = 7400
+admin_user = admin
+admin_pwd = admin
+```
+
+打开浏览器通过 `http://127.0.0.1:7400` 访问 Admin UI，用户名密码默认为 `admin`。
+
+如果想要在外网环境访问 Admin UI，将 7400 端口映射出去即可，但需要重视安全风险。
+
+### 身份验证
+
+服务端和客户端的 common 配置中的 `token` 参数一致则身份验证通过。
+
+### 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。
+
+#### TLS
+
+从 v0.25.0 版本开始 frpc 和 frps 之间支持通过 TLS 协议加密传输。通过在 `frpc.ini` 的 `common` 中配置 `tls_enable = true` 来启用此功能，安全性更高。
+
+为了端口复用，frp 建立 TLS 连接的第一个字节为 0x17。
+
+**注意: 启用此功能后除 xtcp 外，不需要再设置 use_encryption。**
+
+### 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。
+
+### 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 `allow_ports` 来指定：
+
+```ini
+# frps.ini
+[common]
+allow_ports = 2000-3000,3001,3003,4000-50000
+```
+
+`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。
+
+### 端口复用
+
+目前 frps 中的 `vhost_http_port` 和 `vhost_https_port` 支持配置成和 `bind_port` 为同一个端口，frps 会对连接的协议进行分析，之后进行不同的处理。
+
+例如在某些限制较严格的网络环境中，可以将 `bind_port` 和 `vhost_https_port` 都设置为 443。
+
+后续会尝试允许多个 proxy 绑定同一个远端端口的不同协议。
+
+### 限速
+
+#### 代理限速
+
+目前支持在客户端的代理配置中设置代理级别的限速，限制单个 proxy 可以占用的带宽。
+
+```ini
+# frpc.ini
+[ssh]
+type = tcp
+local_port = 22
+remote_port = 6000
+bandwith_limit = 1MB
+```
+
+在代理配置中增加 `bandwith_limit` 字段启用此功能，目前仅支持 `MB` 和 `KB` 单位。
+
+### 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
+
+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
+  ```
+
+### 负载均衡
+
+可以将多个相同类型的 proxy 加入到同一个 group 中，从而实现负载均衡的功能。
+
+目前只支持 TCP 和 HTTP 类型的 proxy。
+
+```ini
+# frpc.ini
+[test1]
+type = tcp
+local_port = 8080
+remote_port = 80
+group = web
+group_key = 123
+
+[test2]
+type = tcp
+local_port = 8081
+remote_port = 80
+group = web
+group_key = 123
+```
+
+用户连接 frps 服务器的 80 端口，frps 会将接收到的用户连接随机分发给其中一个存活的 proxy。这样可以在一台 frpc 机器挂掉后仍然有其他节点能够提供服务。
+
+TCP 类型代理要求 `group_key` 相同，做权限验证，且 `remote_port` 相同。
+
+HTTP 类型代理要求 `group_key, custom_domains 或 subdomain 和 locations` 相同。
+
+### 健康检查
+
+通过给 proxy 加上健康检查的功能，可以在要反向代理的服务出现故障时，将这个服务从 frps 中摘除，搭配负载均衡的功能，可以用来实现高可用的架构，避免服务单点故障。
+
+在每一个 proxy 的配置下加上 `health_check_type = {type}` 来启用健康检查功能。
+
+**type** 目前可选 tcp 和 http。
+
+tcp 只要能够建立连接则认为服务正常，http 会发送一个 http 请求，服务需要返回 2xx 的状态码才会被认为正常。
+
+tcp 示例配置如下：
+
+```ini
+# frpc.ini
+[test1]
+type = tcp
+local_port = 22
+remote_port = 6000
+# 启用健康检查，类型为 tcp
+health_check_type = tcp
+# 建立连接超时时间为 3 秒
+health_check_timeout_s = 3
+# 连续 3 次检查失败，此 proxy 会被摘除
+health_check_max_failed = 3
+# 每隔 10 秒进行一次健康检查
+health_check_interval_s = 10
+```
+
+http 示例配置如下：
+
+```ini
+# frpc.ini
+[web]
+type = http
+local_ip = 127.0.0.1
+local_port = 80
+custom_domains = test.yourdomain.com
+# 启用健康检查，类型为 http
+health_check_type = http
+# 健康检查发送 http 请求的 url，后端服务需要返回 2xx 的 http 状态码
+health_check_url = /status
+health_check_interval_s = 10
+health_check_max_failed = 3
+health_check_timeout_s = 3
+```
+
+### 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`。
+
+### 设置 HTTP 请求的 header
+
+对于 `type = http` 的代理，可以设置在转发中动态添加的 header 参数。
+
+```ini
+# frpc.ini
+[web]
+type = http
+local_port = 80
+custom_domains = test.yourdomain.com
+host_header_rewrite = dev.yourdomain.com
+header_X-From-Where = frp
+```
+
+对于参数配置中所有以 `header_` 开头的参数(支持同时配置多个)，都会被添加到 http 请求的 header 中，根据如上的配置，会在请求的 header 中加上 `X-From-Where: frp`。
+
+### 获取用户真实 IP
+
+#### HTTP X-Forwarded-For
+
+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` 来获取用户真实 IP，默认启用。
+
+#### Proxy Protocol
+
+frp 支持通过 **Proxy Protocol** 协议来传递经过 frp 代理的请求的真实 IP，此功能支持所有以 TCP 为底层协议的类型，不支持 UDP。
+
+**Proxy Protocol** 功能启用后，frpc 在和本地服务建立连接后，会先发送一段 **Proxy Protocol** 的协议内容给本地服务，本地服务通过解析这一内容可以获得访问用户的真实 IP。所以不仅仅是 HTTP 服务，任何的 TCP 服务，只要支持这一协议，都可以获得用户的真实 IP 地址。
+
+需要注意的是，在代理配置中如果要启用此功能，需要本地的服务能够支持 **Proxy Protocol** 这一协议，目前 nginx 和 haproxy 都能够很好的支持。
+
+这里以 https 类型为例:
+
+```ini
+# frpc.ini
+[web]
+type = https
+local_port = 443
+custom_domains = test.yourdomain.com
+
+# 目前支持 v1 和 v2 两个版本的 proxy protocol 协议。
+proxy_protocol_version = v2
+```
+
+只需要在代理配置中增加一行 `proxy_protocol_version = v2` 即可开启此功能。
+
+本地的 https 服务可以通过在 nginx 的配置中启用 **Proxy Protocol** 的解析并将结果设置在 `X-Real-IP` 这个 Header 中就可以在自己的 Web 服务中通过 `X-Real-IP` 获取到用户的真实 IP。
+
+### 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 frpc 都启动成功后，通过 `test.frps.com` 就可以访问到内网的 web 服务。
+
+**注：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 8 个 proxy，命名为 `test_tcp_0, test_tcp_1 ... test_tcp_7`。
+
+### 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。

-### 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:
-
-```
-{

-### 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
-```

-### 服务端管理插件
-
-frp 管理插件的作用是在不侵入自身代码的前提下，扩展 frp 服务端的能力。
-
-frp 管理插件会以单独进程的形式运行，并且监听在一个端口上，对外提供 RPC 接口，响应 frps 的请求。
-
-frps 在执行某些操作前，会根据配置向管理插件发送 RPC 请求，根据管理插件的响应来执行相应的操作。
-
-### RPC 请求
-
-管理插件接收到操作请求后，可以给出三种回应。
-
-* 拒绝操作，需要返回拒绝操作的原因。
-* 允许操作，不需要修改操作内容。
-* 允许操作，对操作请求进行修改后，返回修改后的内容。
-
-### 接口
-
-接口路径可以在 frps 配置中为每个插件单独配置，这里以 `/handler` 为例。
-
-Request
-
-```
-POST /handler
-{
-    "version": "0.1.0",
-    "op": "Login",
-    "content": {
-        ... // 具体的操作信息
-    }
-}
-
-请求 Header
-X-Frp-Reqid: 用于追踪请求
-```
-
-Response
-
-非 200 的返回都认为是请求异常。
-
-拒绝执行操作
-
-```
-{
-   "reject": true,
-   "reject_reason": "invalid user"
-}
-```
-
-允许且内容不需要变动
-
-```
-{
-    "reject": false,
-    "unchange": true
-}
-```
-
-允许且需要替换操作内容
-
-```
-{
-    "unchange": "false",
-    "content": {
-        ... // 替换后的操作信息，格式必须和请求时的一致
-    }
-}
-```
-
-### 操作类型
-
-目前插件支持管理的操作类型有 `Login`、`NewProxy`、`Ping`、`NewWorkConn` 和 `NewUserConn`。
-
-#### Login
-
-用户登录操作信息
-
-```
-{
-    "content": {
-        "version": <string>,
-        "hostname": <string>,

-        "privilege_key": <string>
-    }
-}

-        "proxy_type": <string>,
-        "remote_addr": <string>
-    }

-
-### frps 中插件配置
-
-```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: 插件监听的网络地址。
-path: 插件监听的 HTTP 请求路径。
-ops: 插件需要处理的操作列表，多个 op 以英文逗号分隔。
-
-### 元数据
-
-为了减少 frps 的代码修改，同时提高管理插件的扩展能力，在 frpc 的配置文件中引入自定义元数据的概念。元数据会在调用 RPC 请求时发送给插件。
-
-元数据以 `meta_` 开头，可以配置多个，元数据分为两种，一种配置在 `common` 下，一种配置在各个 proxy 中。
-
-```
-# 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

-So far, there is no mature Go project that does well in parsing `*.ini` files. 
-
-By comparison, we have selected an open source project: `https://github.com/go-ini/ini`.
-
-This library helped us solve most of the key-value matching, but there are still some problems, such as not supporting parsing `map`.
-
-We add our own logic on the basis of this library. In the current situationwhich, we need to complete the entire `Unmarshal` in two steps:
-
-* Step#1, use `go-ini` to complete the basic parameter matching;
-* Step#2, parse our custom parameters to realize parsing special structure, like `map`, `array`.
-
-Some of the keywords in `tag`(like inline, extends, etc.) may be different from standard libraries such as `json` and `protobuf` in Go. For details, please refer to the library documentation: https://ini.unknwon.io/docs/intro.
