they use the hash "#" to save and change the states of the page. HashListener 2.0 make it compatible diferent browsers, and when the browser is not compatible to JavaScript the page works synchronously.
you can download here the libs builded to make this happens.
This sample is builded using PHP and JQuery. It serves to study the principles of BALAH. you can download this demo here.
