Note that if `subdomain_host` is not empty, `custom_domains` should not be the subdomain of `subdomain_host`.
### URL routing
frp support forward http requests to different backward web services by url routing.
`locations` specify the prefix of URL used for routing. frps first searches for the most specific prefix location given by literal strings regardless of the listed order.
```ini
# frpc.ini
[web01]
privilege_mode = true
type = http
local_port = 80
custom_domains = web.yourdomain.com
locations = /
[web02]
privilege_mode = true
type = http
local_port = 81
custom_domains = web.yourdomain.com
locations = /news,/about
```
Http requests with url prefix `/news` and `/about` will be forwarded to **web02** and others to **web01**.
### Connect frps by HTTP PROXY
frpc can connect frps using HTTP PROXY if you set os environment `HTTP_PROXY` or configure `http_proxy` param in frpc.ini file.

同一个 http 或 https 类型的代理中 `custom_domains``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]
privilege_mode = true
type = http
local_port = 80
custom_domains = web.yourdomain.com
locations = /
[web02]
privilege_mode = true
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 HTTP PROXY 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。
