Incorrect headers are sent when performing cross-domain ajax request — at Version 1

Description (last modified by jitter)

When I perform cross-domain ajax request:

    success:function(data, textStatus, jqXHR) {

Script that sends response is:

header('Access-Control-Allow-Origin: *');
echo file_get_contents('cross.json');

cross.json is:

    "name": "konst"

When I do GET request, everything is fine. When I do POST, request is not sent and in chrome it says:

XMLHttpRequest cannot load http://fbtest/cross.php. Request header field x-requested-with is not allowed by Access-Control-Allow-Headers.

I've tracked down the code and found these lines in development version of jquery 1.5:

// Requested-With header
// Not set for crossDomain requests with no content
// (see why at http://trac.dojotoolkit.org/ticket/9486)
// Won't change header if already provided
if ( !( s.crossDomain && !s.hasContent ) && !headers["x-requested-with"] ) {
	headers[ "x-requested-with" ] = "XMLHttpRequest";

So you've got it right - you should NOT set x-requested-with header for cross-domain request. However you do. When I comment out this logic, it works fine. I think there is something wrong with checks you do.
