http://www.hollandonrails.nl/articles/519-jQuery-Hashchange Nowadays web apps do heavily depend on Ajax requests (think GMail). As we all know: by using Ajax request we lose the possibility to bookmark specific pages and the possibility to use the back and forward buttons in our browsers because the url doesn't change. "Ban Alman":http://twitter.com/cowboy wrote javascript solution for this problem. Enter "jquery-hashchange":http://benalman.com/projects/jquery-hashchange-plugin. This jQuery plugin enables very basic bookmarkable #hash history via a cross-browser HTML5 window.onhashchange event. Version 1.3 was recently released. Check it out at "github":http://github.com/cowboy/jquery-hashchange.
