özetle şu şekilde fizy deki olay javascript in document.location elementiyle alıyorlar url i http://fizy.com/#s/1490bs gibi sonra regex le parse ediyorlar.
tabii anlayana

if (document.location.hash.length>1) {
	var re =  new RegExp(/\/s\//);
	var qre =  new RegExp(/\/q\//);
	if ((document.location.pathname).match(re) || (document.location.pathname).match(qre)) {
		document.location.href='/' + document.location.hash;
	} else { 
		var re =  new RegExp(/#s\//);

			if( (document.location.hash).match(re) ) var playIt=document.location.hash.substr(3);
			if( (document.location.hash).match(qre) ) var searchIt=document.location.hash.substr(3);
		}else{
			document.location.href= '/' + document.location.hash.substr(1);
