Package http_dialer provides HTTP(S) CONNECT tunneling net.Dialer. It allows you to establish arbitrary TCP connections (as long as your proxy allows them) through a HTTP(S) CONNECT point.
Readme
A net.Dialer drop-in that establishes the TCP connection over an HTTP CONNECT Tunnel.
Some enterprises have fairly restrictive networking environments. They typically operate HTTP forward proxies that require user authentication. These proxies usually allow HTTPS (TCP to :443) to pass through the proxy using the CONNECT method. The CONNECT method is basically a HTTP-negotiated "end-to-end" TCP stream... which is exactly what net.Conn is :)
Because if you want to call gRPC services which are exposed publicly over :443 TLS over an HTTP proxy, you can't.
Also, this allows you to call any TCP service over HTTP CONNECT... if your proxy allows you to ¯\(ツ)/¯
