If you noticed the change in the browser’s displayed URL, when a hyperlink with a history token is clicked, then can see how the user is able to bookmark a specific state in your app… the token is simply added to the URL in the browser prefixed with a “#”. So, is it possible to add your own history token by typing in the URL for your app and just appending “#mynewtoken” to it? Yes! This is how GWT handles people bookmarking specific states of your application. One thing to keep in mind is that if you end the browser session, and then come into the app, then your app will have to process the initial history state, and it will have to check to see if there is “#mynewtoken” passed in the URL to the browser, and then adjust it’s state accordingly
