CURLOPT_PROXYTYPE - proxy protocol type

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXYTYPE, long type);

Pass one of the values below to set the type of the proxy.

CURLPROXY_HTTP

HTTP Proxy. Default.

CURLPROXY_HTTPS

HTTPS Proxy. (Added in 7.52.0 for OpenSSL, GnuTLS and NSS)

CURLPROXY_HTTP_1_0

HTTP 1.0 Proxy. This is similar to CURLPROXY_HTTP except it uses HTTP/1.0 for any CONNECT tunnelling. It does not change the HTTP version of the actual HTTP requests, controlled by CURLOPT_HTTP_VERSION(3).

CURLPROXY_SOCKS4

SOCKS4 Proxy.

CURLPROXY_SOCKS4A

SOCKS4a Proxy. Proxy resolves URL hostname.

CURLPROXY_SOCKS5

SOCKS5 Proxy.

CURLPROXY_SOCKS5_HOSTNAME

SOCKS5 Proxy. Proxy resolves URL hostname.

Often it is more convenient to specify the proxy type with the scheme part of the CURLOPT_PROXY(3) string.

    /* set the proxy type */
    curl_easy_setopt(curl, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5);
    ret = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
