IE0013: IE XMLHTTP implementation turns 204 response code into bogus 1223 status code
Described here http://dev.jquery.com/ticket/1450, the XMLHTTPRequest object in IE will return a status code of 1223 and drop all response headers if the server returns a HTTP/204 No Content response.
This is caused by an internal design artifact of URLMon (binding returns Operation Aborted (1223) if the server returns no content in response to a request).
Repros in IE9 and earlier. Update: Fixed in IE10.
Workaround: Treat "1223" as equivalent to a 204. Note: HTTP headers remain unavailable in this case.

XMLHttpRequest no longer fails with an “1223” error when a HTTP/204 is returned by a server.
