Hi,

I am developing an application that makes a cross origin AJAX request to an HTTP server written using Netty.

An example of the type of Javascript code being executed is below.

           $.ajax({
               type:"GET",
               url:"http://localhost:5000/someresource",
               data: { id1: "1", id2: "2" },
               success: function(status, textStatus, xhr) {
                   alert("Success")
               },
               error: function(status, textStatus, xhr) {
                   alert("Error")
               }
           });

The problem I am seeing is that on Firefox (3.6.10 and 4.0 beta) the status of the XMLHttpRequest is always 0, regardless of the status of the response. In firebug I can see that the server is returning the correct status for the request, but this is not being pushed through to the XMLHttpRequest object.

Below is the request and response headers being sent

>     Response Headers
>     Content-Type	text/plain; charset=utf-8
>     Content-Length	0
>     Access-Control-Allow-Orig...	http://localhost:9000
>     Cache-Control	no-cache
>     Connection	Keep-Alive
>     Date	Thu, 07 Oct 2010 07:52:08 GMT
>     
>     Request Headers
>     Host	localhost:5000
>     User-Agent	Mozilla/5.0.... 
>     Accept	*/*
>     Accept-Language	en-gb,en;q=0.5
>     Accept-Encoding	gzip,deflate
>     Accept-Charset	ISO-8859-1,utf-8;q=0.7,*;q=0.7
>     Keep-Alive	115
>     Connection	keep-alive
>     Content-Type	application/x-www-form-urlencoded
>     Referer	http://localhost:9000/test
>     Origin	http://localhost:9000

I have tried executing the code in Chrome, Opera and Safari and they all work fine. Is this something I am doing or a bug in Firefox?

Thanks in advance.
