.SH DESCRIPTION
Pass one of the values below to set the type of the proxy.
.IP CURLPROXY_HTTP
HTTP Proxy. Default.
.IP 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.)
.IP CURLPROXY_HTTPS2
HTTPS Proxy and attempt to speak HTTP/2 over it. (Added in 8.1.0)
.IP 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 \fICURLOPT_HTTP_VERSION(3)\fP.
.IP CURLPROXY_SOCKS4
SOCKS4 Proxy.
.IP CURLPROXY_SOCKS4A
SOCKS4a Proxy. Proxy resolves URL hostname.
.IP CURLPROXY_SOCKS5
SOCKS5 Proxy.
.IP CURLPROXY_SOCKS5_HOSTNAME
SOCKS5 Proxy. Proxy resolves URL hostname.
.PP
Often it is more convenient to specify the proxy type with the scheme part of
the \fICURLOPT_PROXY(3)\fP string.
