CURLOPT_HTTP09_ALLOWED(3)  curl_easy_setopt options  CURLOPT_HTTP09_ALLOWED(3)

NAME
       CURLOPT_HTTP09 -	allow HTTP/0.9 response

SYNOPSIS
       #include	<curl/curl.h>

       CURLcode	 curl_easy_setopt(CURL	*handle,  CURLOPT_HTTP09_ALLOWED, long
       allowed);

DESCRIPTION
       Pass the	long argument allowed set to 1L	to allow HTTP/0.9 responses.

       A HTTP/0.9 response is a	server response	entirely without  headers  and
       only  a	body. You can connect to lots of random	TCP services and still
       get a response that curl	might consider to be HTTP/0.9!

DEFAULT
       curl allowed HTTP/0.9 responses by default before 7.66.0

       Since 7.66.0, libcurl requires this option set to 1L to allow  HTTP/0.9
       responses.

PROTOCOLS
       HTTP

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl)	{
	 CURLcode ret;
	 curl_easy_setopt(curl,	CURLOPT_URL, "https://example.com/");
	 curl_easy_setopt(curl,	CURLOPT_HTTP09_ALLOWED,	1L);
	 ret = curl_easy_perform(curl);
       }

AVAILABILITY
       Option added in 7.64.0, present along with HTTP.

RETURN VALUE
       Returns CURLE_OK	if HTTP	is supported, and CURLE_UNKNOWN_OPTION if not.
