Ah, I had a look at the source code, maybe there is something bad. You
are using setTimeout to reinvoke the method after 250 msec, but you
are not sure if the method before is done in 250 msec. I would change
the code like this:
function progressUpdate() {
updateCounter++;
ValenceWap.ajax.main.getResponse(updateCounter, progressUpdate_Callback);
loopCount.innerHTML = updateCounter;
}
function progressUpdate_Callback(ret) {
if(ret.error == null && ret.value != null) {
var progress = ret.value;
callback.innerHTML = progress;
}
setTimeout(progressUpdate, 250);
}
The problem in your code is that the waitingCallback variable is not
threadsafe because of the two concurrent xmlhttp requests. It can
happen that there are two concurrent requests running and the variable
will be false, then the next request will be queued, no real problem,
but it will maybe queue more and more, and you have more requests than
you want to have. If the queue will be very large, the two concurrent
connections will be used to do the requests and other requests or
pressing F5 will get in problem.
My script will call the method every 250 msec after the request is done.
I hope this will help you?!

Michael
