CURLOPT_HTTPPROXYTUNNEL(3) curl_easy_setopt options CURLOPT_HTTPPROXYTUNNEL(3)NAMECURLOPT_HTTPPROXYTUNNEL - tunnel through HTTP proxy
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HTTPPROXYTUNNEL, long
tunnel);
DESCRIPTION
Set the parameter to 1 to make libcurl tunnel all operations through
the HTTP proxy. There is a big difference between using a proxy and to
tunnel through it. If you don't know what this means, you probably
don't want this tunneling option.
Tunneling essentially means that a CONNECT is sent to the proxy, asking
it to connect to a remote host on a specific port number and then the
traffic is just passed through the proxy. Proxies tend to whitelist
specific port numbers it allows CONNECT requests to and often only port
80 and 443 are allowed.
When using this, it only makes sense to use CURLOPT_PROXYTYPE(3) set to
a HTTP proxy.
