.TH CURLOPT_HTTP09_ALLOWED 3 "17 Dec 2018" "libcurl 7.64.0" "curl_easy_setopt options"
.SH NAME
CURLOPT_HTTP09 \- allow HTTP/0.9 response
.SH SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HTTP09_ALLOWED, long allowed);
.SH DESCRIPTION
Pass the long argument \fIallowed\fP 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!
.SH 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.
.SH PROTOCOLS
HTTP
.SH EXAMPLE
.nf
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);
}
.fi
.SH AVAILABILITY
Option added in 7.64.0, present along with HTTP.
