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.

    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.

DEFAULT
CURLPROXY_HTTP
