CURLOPT_PROXYTYPE(3) Library Functions Manual CURLOPT_PROXYTYPE(3)

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.

HTTP Proxy. Default.
HTTPS Proxy using HTTP/1. (Added in 7.52.0 for OpenSSL and GnuTLS. Since 7.87.0, it also works for BearSSL, mbedTLS, rustls, Schannel, Secure Transport and wolfSSL.)
HTTPS Proxy and attempt to speak HTTP/2 over it. (Added in 8.1.0)
HTTP 1.0 Proxy. This is similar to CURLPROXY_HTTP except it uses HTTP/1.0 for any CONNECT tunneling. It does not change the HTTP version of the actual HTTP requests, controlled by CURLOPT_HTTP_VERSION(3).
SOCKS4 Proxy.
SOCKS4a Proxy. Proxy resolves URL hostname.
SOCKS5 Proxy.
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
