+Help: Operate through a HTTP proxy tunnel (using CONNECT)
+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.
