function url(value) {
	return value + (/\?/.test(value) ? "&" : "?") + new Date().getTime() + "" + parseInt(Math.random()*100000);
}
Add random number to url to stop IE from caching

@example url("data/test.html")
@result "data/test.html?10538358428943"

@example url("data/test.php?foo=bar")
@result "data/test.php?foo=bar&10538358345554"
