- Creating mobile Web applications with HTML 5, Part 2: Unlock local storage for mobile Web applications with HTML 5
One of the most useful new features in HTML 5 is the standardization of local storage. Finally, Web developers can stop trying to fit all client-side data into 4 KB Cookies. Now you can store large amounts of data on the client with a simple API. This is a perfect mechanism for caching, so you can dramatically improve the speed of your application—a critical factor for mobile Web applications that rely on much slower connections than their desktop brothers.
