        !            34: Pass a pointer to a linked list of \fIaliases\fP to be treated as valid HTTP
        !            35: 200 responses.  Some servers respond with a custom header response line.  For
        !            36: example, SHOUTcast servers respond with "ICY 200 OK". Also some very old
        !            37: Icecast 1.3.x servers will respond like that for certain user agent headers or
        !            38: in absence of such. By including this string in your list of aliases,
        !            39: the response will be treated as a valid HTTP header line such as
        !            40: "HTTP/1.0 200 OK".
        !            41: 
        !            42: The linked list should be a fully valid list of struct curl_slist structs, and
        !            43: be properly filled in.  Use \fIcurl_slist_append(3)\fP to create the list and
        !            44: \fIcurl_slist_free_all(3)\fP to clean up an entire list.
        !            45: 
        !            46: The alias itself is not parsed for any version strings. The protocol is
        !            47: assumed to match HTTP 1.0 when an alias match.
