NAME

       CURLOPT_HAPROXY_CLIENT_IP - set HAProxy PROXY protocol client IP

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HAPROXY_CLIENT_IP,
                                 char *client_ip);

DESCRIPTION

       When  this  parameter  is set to a valid IPv4 or IPv6 numerical address, the library sends
       this address as client address in the HAProxy PROXY protocol v1 header at beginning of the
       connection.

       This  option  is  an  alternative  to  CURLOPT_HAPROXYPROTOCOL(3) as that one cannot use a
       specified address.

DEFAULT

       NULL, no HAProxy header is sent

PROTOCOLS

           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
