11       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HAPROXYPROTOCOL,

DESCRIPTION

15       A  long  parameter  set to 1 tells the library to send an HAProxy PROXY
16       protocol v1 header at beginning of the connection. The  default  action
17       is not to send this header.
18
19       This option is primarily useful when sending test requests to a service
20       that expects this header.
21
22       Most applications do not need this option.
