Hello, we strive to provide the web socket technology to all internet users and hence jWebSocket now also supports the older versions of Internet Explorer 7 and 6. It’s already available in the nightly builds section at http://code.google.com/p/jwebsocket/source/browse/#svn/trunk and will be part of the coming jWebSocket v0.9. Let us know your further requirements. Best Regards, Alex – a.schulze@jwebsocket.org
