A simple example to show the use of the Application Cache interface.
For a thorough exploration of this topic, read A Beginner's Guide to Using the Application Cache, an article by Eric Bidelman originally published on HTML5Rocks.
Application Cache allows you to specify which files the browser should cache and make available to offline users. Your app will load and work correctly, even if the user presses the refresh button while offline.
To see this example in action, make changes to index.html and then reload
the app. Your changes don't show up because the browser displays a cached
version of index.html. Next, change the date or version number in
appcache.mf, and reload once more. You'll be prompted to load the new version.
