First, try the chat, it's the little black box in the bottom right corner!

Comet is all about corporate firewalls, because you want to reach everyone, everywhere, you need to use HTTP on port 80. Now you can push data over HTTP on port 80 in real-time.

Rupy enables you to connect 10000+ concurrent users with one server, this number can scale to 30000+ depending on your application.

In web-browser context also known as 'Ajax Push', see Comet for more information.

Download the talk application together with the latest rupy and extract them to the same folder. Go to the talk/ folder and start rupy with either the talk.bat or talk.sh script depending on your OS. Then run ant in that same talk/ folder, this should build and deploy the talk.jar application to your rupy server. Lastly, browse to http://localhost:8000/talk.html and chat in real-time over HTTP!

If you want to use rupy talk with apache enable mod_proxy and add something along these lines:

<VirtualHost *:80>
        ProxyPass /poll http://localhost:8000/poll
        ProxyPass /broadcast http://localhost:8000/broadcast
</VirtualHost>
