Web Storage (Second Edition) is a W3C Recommendation

April 19th, 2016

The Web Platform Working Group has published a W3C Recommendation of Web Storage (Second Edition). This specification defines an API for persistent data storage of key-value pair data in Web clients. It introduces two related mechanisms, similar to HTTP session cookies, for storing name-value pairs on the client side. The first mechanism is designed for scenarios where the user is carrying out a single transaction, but could be carrying out multiple transactions in different windows at the same time. The second mechanism is designed for storage that spans multiple windows, and lasts beyond the current session.
