HTML5 Web Messaging Draft Published

19 November 2010

The Web Applications Working Group has published the First Public Working Draft of HTML5 Web Messaging. This specification defines two mechanisms for communicating between browsing contexts in HTML documents. Cross document messaging allows documents to communicate with each other regardless of their source domain, in a way designed to not enable cross-site scripting attacks. Channel messaging allows independent pieces of code (e.g. running in different browsing contexts) to communicate directly. Learn more about the Rich Web Client Activity.
