+# NAME
+
+CURLOPT_HTTP200ALIASES - alternative matches for HTTP 200 OK
+
+# SYNOPSIS
+
+~~~c
+#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 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 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.
+
+Using this option multiple times makes the last set list override the previous
+ones. Set it to NULL to disable its use again.
+
+libcurl does not copy the list, it needs to be kept around until after the
+transfer has completed.
+
+# DEFAULT
+
+NULL
+
+# %PROTOCOLS%
+
+# EXAMPLE
+
+~~~c
+int main(void)
+{
+  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%
+
+# RETURN VALUE
+
+curl_easy_setopt(3) returns a CURLcode indicating success or error.
+
+CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
+libcurl-errors(3).
