AJAX DELETE request never completes in IE

[MoonScript]

When you issue an AJAX DELETE request, IE stops at readyState 2 (headers received), so the success/error/complete callback functions never get executed. This makes sense since DELETE (and PUT) requests should return an HTTP 204 (No Content) response, so there is no body. You might have to add another else-if in your onreadystatechange handler when the request type is 'DELETE', to fire the success and complete callbacks when readyState === 2. Or, in a future version of jQuery, provide another $.ajax option that would provide the means to override the onreadystatechange handler with your own custom code.

Note: I kept getting an 'Unspecified error' in IE when I tried to check the XHR's status property at readyState 2, so I was never able to call the error callback.

Does the DELETE call to the server actually succeed? Methods other than GET and POST have traditionally not been well-supported across all browsers.

Yes, the DELETE request does hit the server successfully. I am able to monitor the HTTP traffic using Fiddler, and I can see the request being made, and the HTTP 204 response being received.

Also, I just verified that the same problem is happening in the Safari browser (not Chrome, though). It stops at readyState===2.

P.S. I am also seeing this problem in Safari when using the PUT method.

We haven't gotten very far without code. Can you provide some? A jsfiddle test case would be ideal but if you have something site-specific please put a page up there.
