………………………………………………

Using the cache interface gives your application three advantages:

Offline browsing – users can navigate your full site when they’re offline
Speed – cached resources are local, and therefore load faster.
Reduced server load – the browser will only download resources from the server that have changed.
The Application Cache (or AppCache) allows a developer 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 they’re offline.
