The HTML 5 specification provides a new mechanism for client-side data storage: JavaScript database support. HTML 5 is currently in development by the Web Hypertext Application Technology Working Group (WHATWG).

JavaScript database support is available in Safari 3.1 and later, and in iPhone OS 2.0 and later.

You should read this documentation if you are a web developer who wants to store data locally on a user’s computer in amounts beyond what can reasonably be stored in an HTTP cookie.
