.TH CURLOPT_HAPROXY_CLIENT_IP 3 "2025-06-27" libcurl
.SH NAME
CURLOPT_HAPROXY_CLIENT_IP \- set HAProxy PROXY protocol client IP
.SH SYNOPSIS
.nf
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HAPROXY_CLIENT_IP,
char *client_ip);
.fi
.SH 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 \fICURLOPT_HAPROXYPROTOCOL(3)\fP as that one cannot
use a specified address.
Using this option multiple times makes the last set string override the
previous ones. Set it to NULL to disable its use again.
The application does not have to keep the string around after setting this
option.
.SH DEFAULT
NULL, no HAProxy header is sent
.SH PROTOCOLS
This functionality affects all supported protocols
.SH EXAMPLE
.nf
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode ret;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
curl_easy_setopt(curl, CURLOPT_HAPROXY_CLIENT_IP, "1.1.1.1");
ret = curl_easy_perform(curl);
}
}
.fi
.SH AVAILABILITY
Added in curl 8.2.0
.SH RETURN VALUE
\fIcurl_easy_setopt(3)\fP returns a CURLcode indicating success or error.
CURLE_OK (0) means everything was OK, non\-zero means an error occurred, see
\fIlibcurl\-errors(3)\fP.
