Can I use JavaScript to subscribe to WCF WSDualHtt

问题:

I have a web site that needs data to be pushed to it. Unfortunately, I'm not aware of any other methods besides using HTML 5 WebSockets (I can't garauntee my clients will have HTML5 browers) and Comet (I'm not using java/tomcat).

I am not a big fan of using server-side ASP.NET for this particular project, and would prefer to use ASP.NET MVC or something like it. Is it possible to tie JavaScript in with a duplex service?

Well actually you can leverage the pollingduplex binding used for silverlight clients in javascript. There is an interesting blog post on this by tomek over here: http://tomasz.janczuk.org/2009/07/pubsub-sample-using-http-polling-duplex.html
