Remove the PROTOCOLS section from the source files completely and instead generate them based on the header data in the curldown files. It also generates TLS backend information for options marked for TLS as protocol. Closes #13175

# 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.
|
|
|
|
# EXAMPLE
|
|
|
|
~~~c
|
|
int main(void)
|
|
{
|
|
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.
