CURLOPT_HTTP09_ALLOWED 3 "December 17, 2018" "libcurl 7.64.1" "curl_easy_setopt options"
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, while 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 allows HTTP/0.9 responses by default.
A future curl version will require this option to be set 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.
