| # Proxy |
| |
| HTTP CONNECT proxies are supported by default in gRPC. The proxy address can be |
| specified by the environment variables HTTP_PROXY, HTTPS_PROXY and NO_PROXY (or |
| the lowercase versions thereof). |
| |
| ## Custom proxy |
| |
| Currently, proxy support is implemented in the default dialer. It does one more |
| handshake (a CONNECT handshake in the case of HTTP CONNECT proxy) on the |
| connection before giving it to gRPC. |
| |
| If the default proxy doesn't work for you, replace the default dialer with your |
| custom proxy dialer. This can be done using |
| [`WithDialer`](https://godoc.org/google.golang.org/grpc#WithDialer). |
