Provided by: libcurl4-doc_8.12.1-2ubuntu1_all bug

NAME

       CURLOPT_HTTP09_ALLOWED - 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.

       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

       0

PROTOCOLS

       This functionality affects http only

EXAMPLE

       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);
         }
       }

HISTORY

       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.

AVAILABILITY

       Added in curl 7.64.0

RETURN VALUE

       curl_easy_setopt(3) returns a CURLcode indicating success or error.
