# NAME
|
|
|
|
CURLOPT_HAPROXYPROTOCOL - send HAProxy PROXY protocol v1 header
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HAPROXYPROTOCOL,
|
|
long haproxy_protocol);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
A long parameter set to 1 tells the library to send an HAProxy PROXY
|
|
protocol v1 header at beginning of the connection. The default action is not to
|
|
send this header.
|
|
|
|
This option is primarily useful when sending test requests to a service that
|
|
expects this header.
|
|
|
|
Most applications do not need this option.
|
|
|
|
# DEFAULT
|
|
|
|
0, do not send any HAProxy PROXY protocol header
|
|
|

curl_easy_setopt(curl, CURLOPT_HAPROXYPROTOCOL, 1L);
