Specify alternative matches for http 200 ok
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HTTP200ALIASES, struct curl_slist *aliases);
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, IceCast servers respond with "ICY 200 OK". 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 curl_slist_append(3) to create the list and 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.
Added in 7.10.3
Returns CURLE_OK if HTTP is supported, and CURLE_UNKNOWN_OPTION if not.
