With web storage, web applications can store data locally within the user's browser.
Before HTML5, application data had to be stored in cookies, included in every server request. Web storage is more secure, and large amounts of data can be stored locally, without affecting website performance.

Web storage is per origin (per domain and protocol). All pages, from one origin, can store and access the same data.
