HTTP CONNECT proxies are supported by default in gRPC. The proxy address can be
specified by the environment variables HTTPS_PROXY
and NO_PROXY
. (Note that
these environment variables are case insensitive.)
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
WithContextDialer
.
