In this video session, Jef covers the WebSockets fundamentals, demonstrate a proof of concept that could be used in various fire department web applications and deep-dive into the code of this proof of concept.
"While the WebSockets API specification is not stable yet, various browser vendors have already implemented a prototype in their latest browser versions. Microsoft released their WebSockets prototype in December 2010. While there's no native implementation of WebSockets in IE9 just yet, for now they're providing a solution which works cross-browser, relying on a Silverlight client. Server-side a Windows Communication Foundation server is made available, which implements the latest version of the WebSockets protocol."
