Unsubscribe event sends a synchronous http call for cross domains and no cookie and session information is present in this request

[Swaroop-Bhupathiraju]

I use jsonp to do a cross domain call to the atmosphere server for normal http requests.
When the browser supports websockets, i use websocket communication but when a unsubscribe event happens, i think atmosphere sends the disconnect call (transport=close) as a regular http call to the server but not as a jsonp call.
In case of cross domain http requests, the session and cookie is not sent
JSONP might not be possible here as this will be a synchronous request

function disconnect() {
if (_request.enableProtocol && !_request.firstMessage) {
var query = "X-Atmosphere-Transport=close&X-Atmosphere-tracking-id=" + _request.uuid;
var url = _request.url.replace(/([?&])=[^&]*/, query);
url = url + (url === _request.url ? (/\?/.test(_request.url) ? "&" : "?") + query : "");

                if (_request.connectTimeout > 0) {
                    jQuery.ajax({
                        url: url,
                        async: false,
                        timeout: _request.connectTimeout
                    });
