1# Proxy
2
3HTTP CONNECT proxies are supported by default in gRPC. The proxy address can be
4specified by the environment variables HTTP_PROXY, HTTPS_PROXY and NO_PROXY (or
5the lowercase versions thereof).

7## Custom proxy
8
9Currently, proxy support is implemented in the default dialer. It does one more
10handshake (a CONNECT handshake in the case of HTTP CONNECT proxy) on the
11connection before giving it to gRPC.
12
13If the default proxy doesn't work for you, replace the default dialer with your
14custom proxy dialer. This can be done using
15[`WithDialer`](https://godoc.org/google.golang.org/grpc#WithDialer).
