SPDX-License-Identifier: curl Long: proxytunnel Short: p Help: Operate through an HTTP proxy tunnel (using CONNECT) See-also: proxy Category: proxy Example: --proxytunnel -x http://proxy $URL Added: 7.3 Multi: boolean --- When an HTTP proxy is used --proxy, this option will make curl tunnel through the proxy. 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.
