See-also: proxy

-When an HTTP proxy is used --proxy, this option will cause non-HTTP protocols
-to attempt to tunnel through the proxy instead of merely using it to do
-HTTP-like operations. The tunnel approach is made with the HTTP proxy CONNECT
-request and requires that the proxy allows direct connect to the remote port
-number curl wants to tunnel through to.

To suppress proxy CONNECT response headers when curl is set to output headers
use --suppress-connect-headers.
