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 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.)
CURLPROXY_HTTPS2: HTTPS Proxy and attempt to speak HTTP/2 over it. (Added in 8.1.0)
CURLPROXY_HTTP_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).
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.
