CURLOPT_HTTP09_ALLOWED(3) curl_easy_setopt options CURLOPT_HTTP09_ALLOWED(3) 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. 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 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. SEE ALSO CURLOPT_SSLVERSION(3), CURLOPT_HTTP_VERSION(3), libcurl 7.72.0 August 05, 2019 CURLOPT_HTTP09_ALLOWED(3)
