Dynamic web applications that avoid page refreshes are very powerful, but this normally means that the Back and Forward buttons stop working in the browser. In addition, it can be hard to give the user an URL that can be bookmarked.

However, Dojo provides a solution to these issues, allowing a web application to capture the Back and Forward button clicks, and set a unique URL in the browser's location field. The solution is to use dojo.undo.browser.
