Web storage, sometimes known as DOM storage (Document Object Model storage), is a standard JavaScript API provided by web browsers. It enables websites to store persistent data on users' devices similar to cookies, but with much larger capacity[1] and no information sent in HTTP headers.[2] There are two main web storage types: local storage and session storage, behaving similarly to persistent cookies and session cookies respectively. Web Storage is standardized by the World Wide Web Consortium (W3C)[3] and WHATWG,[4] and is supported by all major browsers.
