NAME

CURLOPT_PROXYTYPE - proxy protocol type

SYNOPSIS

#include <curl/curl.h>

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

DESCRIPTION

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 very 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.

DEFAULT

CURLPROXY_HTTP
