- .SH NAME
- CURLOPT_HTTPPROXYTUNNEL \- tunnel through HTTP proxy
- .SH SYNOPSIS
- #include <curl/curl.h>
- CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HTTPPROXYTUNNEL, long tunnel);
- .SH 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.
