A Strophe plugin by iAdvize that use the XdomainRequest if found (Internet Explorer)
Strophe.addConnectionPlugin("xdomainrequest", {
init: function () {
if (window.XDomainRequest) {
Strophe.debug("using XdomainRequest for IE");
// override thee send method to fire readystate 2
XDomainRequest.prototype.oldsend = XDomainRequest.prototype.send;
XDomainRequest.prototype.send = function() {
XDomainRequest.prototype.oldsend.apply(this, arguments);
this.readyState = 2;
try {
} catch (e) {}
// replace Strophe.Request._newXHR with the xdomainrequest version
Strophe.Request.prototype._newXHR = function () {
var fireReadyStateChange = function (xhr, status) {
xhr.status = status;
xhr.readyState = 4;
try {
} catch (e) {}
var xhr = new XDomainRequest();
xhr.readyState = 0;
xhr.onreadystatechange = this.func.bind(null, this);
xhr.onload = function () {
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = "false";
xhr.responseXML = xmlDoc;
fireReadyStateChange(xhr, 200);
xhr.onerror = function () {
fireReadyStateChange(xhr, 500);
xhr.ontimeout = function () {
fireReadyStateChange(xhr, 500);
return xhr;
} else {
Strophe.error("XDomainRequest not found. Falling back to native XHR implementation.");

Thanks for this, works like a charm :)

Thanks a loooooooooooooooooooot!! it works very smoothly.

Works great for me on IE9 win7. Just a note: I had to put this at the bottom of strophe.js right after:

if (callback) {
callback(Strophe, $build, $msg, $iq, $pres);

I've found a looping request on IE9 when user loses connection after some time of inactivity.

The server returns this message:
2015-04-09 10:43:18.674 [pool-11-thread-7] BoshConnectionManager.processSocketData() INFO: There is no session with given SID = 6b9698c7-0e37-40a2-bf8a-e7783a8958f0. Closing invalid connection

The client receives a 404 response but Strophe is not able to disconnect and try again ....
