-When forwarding to a local port, frp does not modify the tunneled HTTP requests at all, they are copied to your server byte-for-byte as they are received.

+
+### 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

+# 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

+Package context stores values shared during a request lifetime.
+
+Note: gorilla/context, having been born well before `context.Context` existed,
+does not play well > with the shallow copying of the request that
+[`http.Request.WithContext`](https://golang.org/pkg/net/http/#Request.WithContext)
+(added to net/http Go 1.7 onwards) performs. You should either use *just*
+gorilla/context, or moving forward, the new `http.Request.Context()`.
+
+For example, a router can set variables extracted from the URL and later
+application handlers can access those values, or it can be used to store
+sessions values to be saved at the end of a request. There are several
+others common uses.
+
+The idea was posted by Brad Fitzpatrick to the go-nuts mailing list:
+
+	http://groups.google.com/group/golang-nuts/msg/e2d679d303aa5d53
+
+Here's the basic usage: first define the keys that you will need. The key
+type is interface{} so a key can be of any type that supports equality.
+Here we define a key using a custom int type to avoid name collisions:
+
+	package foo
+
+	import (
+		"github.com/gorilla/context"
+	)
+
+	type key int
+
+	const MyKey key = 0
+
+Then set a variable. Variables are bound to an http.Request object, so you
+need a request instance to set a value:
+
+	context.Set(r, MyKey, "bar")
+
+The application can later access the variable using the same key you provided:
+
+	func MyHandler(w http.ResponseWriter, r *http.Request) {
+		// val is "bar".
+		val := context.Get(r, foo.MyKey)
+
+		// returns ("bar", true)
+		val, ok := context.GetOk(r, foo.MyKey)
+		// ...
+	}
+
+And that's all about the basic usage. We discuss some other ideas below.
+
+Any type can be stored in the context. To enforce a given type, make the key
+private and wrap Get() and Set() to accept and return values of a specific
+type:
+
+	type key int
+
+	const mykey key = 0
+

+
+Variables must be cleared at the end of a request, to remove all values
+that were stored. This can be done in an http.Handler, after a request was
+served. Just call Clear() passing the request:
+
+	context.Clear(r)
+
+...or use ClearHandler(), which conveniently wraps an http.Handler to clear
+variables at the end of a request lifetime.
+
+The Routers from the packages gorilla/mux and gorilla/pat call Clear()
+so if you are using either of them you don't need to clear the context manually.
