NAME
       CURLOPT_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.

       To suppress proxy CONNECT response headers from user callbacks use CURLOPT_SUPPRESS_CONNECT_HEADERS(3).
