If you don't mind that your server is polled on a regular base, just place this line into the the header part of your html page :


Then the browser refreshes the page automatically every 10 seconds.

There's something called Seaside-WebSocket-Core in [1]. It's an
abstraction over the WebSocket support in Swazoo and WebClient. It
certainly could be extended to support Zinc. Having that said I'm not
really sure how well this fits into Seaside. The request/response
model is quite central to Seaside and not sure wether it makes sense
to run WebSockets inside a request context. OTOH this might be another
nice application for continuations. I guess we'll just have to
experiment a bit.
