The problem is that websocket (as any other HTML5 spec) has chages a bit in the last two years making some useful libraries outdated and not definitely working.

But if you want to go with websockets as lightweight as possible, both your server and your client (browser) need to support it in the most up-to-date way. > > I am always careful with such decisions.

It adheres somehow to the server-event specifications (that is another way to say server->client communication). Anyway I'd give atmosphere a try. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
