IE mangles HTTP response status code 204 to 1223

I've come across some strange behavior in IE7. Sometimes when an

XmlHttpRequest receives a 204 (No Content) HTTP status code on the

response, IE sets the XmlHttpRequest object's status property to

1223. In my code, this seems to be happening when my server is

returning a 204 from a PUT request - IE seems to be handling the 204

from a DELETE request okay.

Anyhow, jQuery's httpSuccess function is (quite understandably)

interpreting the 1223 response as a failure. I tacked on another

condition to the end of the if statement (line 1939 in jquery-

jQuery.browser.msie && r.status == 1223

This seems to fix the problem. However, my overall jQuery knowledge

is pretty limited, so I'm not aware of any potential side effects.

A quick Google search turns up a few references to this bug on the

intertubes, but I can't find anything on MSDN (surprise surprise).

Yahoo's toolkit normalizes the 1223 response back to 204 (search for 1223 below):

Any chance a fix for this can make it into the next version of jQuery?

Fixed in [3977]. Now 1223 status is treated as success. I couldn't write code to normalize the status because jQuery uses the actual XHR object. Also I couldn't reproduce the bug since I don't know exactly what causes it, but I did a fair amount of internet reading and it does appear to be an actual bug so I think the fix is still warrented.
