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, the library will not send this address
       in the HAProxy PROXY protocol v1 header at beginning of the connection.

       This option is primarily useful when sending test requests to verify  that  a  service  is
       working as intended.

DEFAULT

       no HAProxy header will be sent
