In this page you can test a sessionStorage usage example. A sessionStorage object persists only in this tab or window. If your browser has not a native sessionStorage object, You should be able to use sessionStorage thanks to my porting.
Try to reload this page or try to surf elsewhere, but please, copy this page url somewhere and try to come back whenever you want as long as you use the same window.
