One of the issues that largely remains unsolved in AJAX applications is the ability to bookmark (say, add to the Favourites) the page with all the AJAX added info on it. This very cool javascript library allows one to save the state of the page using the window.location.hash variable, which holds the string after the # character, also called a hash.
Javascript can modify and read this value with no refresh of the page. Also, if you have anchors in your page, like... <a name="hash" Javascript code like
will scroll the page there.
