HTML5 introduces new methods for enabling a web site or web application to function without a network connection. When you’re working on a mobile connection and your signal drops, or you just have no connection to the internet for whatever reason, having some level of access is better than nothing. In this article, we’ll look at how the application cache can store resources to be used by the browser when it’s offline, granting your users partial access to your web site or application.

Web apps that work offline are still uncommon, and there aren't a lot of "real life" implementation examples on the Web.

Ian Collins has created DBScriptCache, a JavaScript program that "automatically caches script files in the browser's HTML5 client-side database. Rather than including your scripts using script tags, you include them using this script. The first time a user views the page the scripts will be pulled into the db and stored. On subsequent visits the scripts will be loaded from the db cache and not from your server. The script will continue to come from the cache until you supply a new version number or change the name of the script."
