Why? What's wrong with using the AJAX request status, which is the canonical way to determine the status of the request (and thus success or failure)?

There might be a legitimate reason for this restriction (though at first glance it appears not), but if so then it's because you're doing something unusual, such as making requests that you expect to "fail". If this is the case, then you'd need to make clear exactly what the constraints are anyway.

Failing that, just check the status and ensure that the remote server is returning the right status for requests (if it's under your control).
