# NAME
|
|
|
|
CURLOPT_HTTP09_ALLOWED - allow HTTP/0.9 response
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#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.
|
|
|
|
An 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

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);
|
|
}
|
|
}

Option added in 7.64.0, present along with HTTP.
