.SH NAME
CURLOPT_HTTP200ALIASES \- alternative matches for HTTP 200 OK
.SH SYNOPSIS
.nf
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HTTP200ALIASES,
struct curl_slist *aliases);
.fi
.SH DESCRIPTION
Pass a pointer to a linked list of \fIaliases\fP 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 old Icecast
1.3.x servers respond like that for certain user agent headers or in absence
of such. By including this string in your list of aliases, the response gets
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 \fIcurl_slist_append(3)\fP to create the list and
\fIcurl_slist_free_all(3)\fP 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.
.SH DEFAULT
NULL
.SH PROTOCOLS
This functionality affects http only
.SH EXAMPLE
.nf
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {

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 */
}
