Description
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
- 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-1.1.3.1.js):
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.
