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.
