Exposes a variable openHTTPs which keeps track of how many XMLHttpRequests you have active.

	<script>
	(function() {
	var oldOpen = XMLHttpRequest.prototype.open;
	window.openHTTPs = 0;
	XMLHttpRequest.prototype.open = function(method, url, async, user, pass) {
	window.openHTTPs++;
	this.addEventListener("readystatechange", function() {
	if(this.readyState == 4) {
	window.openHTTPs--;
	}
