Free refresh / reload page only once JavaScript

This script will reload the page ONCE after the initial page load. I did NOT write this script but found it to be quite useful so I thought I would pass it along.



<script>
var reloaded = false;
var loc=""+document.location;
loc = loc.indexOf("?reloaded=")!=-1?loc.substring(loc.indexOf("?reloaded=")+10,loc.length):"";
loc = loc.indexOf("&")!=-1?loc.substring(0,loc.indexOf("&")):loc;
reloaded = loc!=""?(loc=="true"):reloaded;

function reloadOnceOnly() {
	if (!reloaded)
	window.location.replace(window.location+"?reloaded=true");
}
reloadOnceOnly();
</script>
