CURLOPT_HTTP200ALIASES(3)  curl_easy_setopt options  CURLOPT_HTTP200ALIASES(3)

NAME
       CURLOPT_HTTP200ALIASES - specify alternative matches for HTTP 200 OK

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HTTP200ALIASES,
                                 struct curl_slist *aliases);

DESCRIPTION
       Pass a pointer to a linked list of aliases to be treated as valid HTTP
       200 responses.  Some servers respond with a custom header response
       line.  For example, SHOUTcast servers respond with "ICY 200 OK". Also
       some very old Icecast 1.3.x servers will respond like that for certain
       user agent headers or in absence of such. By including this string in
       your list of aliases, the response will be treated as a valid HTTP
       header line such as "HTTP/1.0 200 OK".

       The linked list should be a fully valid list of struct curl_slist
       structs, and be properly filled in.  Use _slist_append&section=3">curl_slist_append(3) to create
       the list and _slist_free_all&section=3">curl_slist_free_all(3) to clean up an entire list.

       The alias itself is not parsed for any version strings. The protocol is
       assumed to match HTTP 1.0 when an alias match.

DEFAULT
       NULL

PROTOCOLS
       HTTP

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         struct curl_slist *list;
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

         list = curl_slist_append(NULL, "ICY 200 OK");
         list = curl_slist_append(list, "WEIRDO 99 FINE");

         curl_easy_setopt(curl, CURLOPT_HTTP200ALIASES, list);
         curl_easy_perform(curl);
         curl_slist_free_all(list); /* free the list again */
       }

AVAILABILITY
       Added in 7.10.3

RETURN VALUE
       Returns CURLE_OK if HTTP is supported, and CURLE_UNKNOWN_OPTION if not.
