Question

I’m creating a web application that allows users to make changes through Javascript. There is not yet any AJAX involved, so those changes to the DOM are being made purely in the user’s local browser.

But how can I make those DOM changes occur in the browser of anyone else who is viewing that page at the time? I assume AJAX would be involved here. Perhaps the page could just send the entire, JS-modified source code back to the server and then the other people viewing would receive very frequent AJAX updates?

Screen sharing would obviously be an easy work-around, but I’m interested to know if there’s a better way, such as described above.

Thanks!

You are talking about comet, for an easy implementation i’d suggest:

• http://www.ape-project.org/

and also check these:

• http://meteorserver.org/
• http://activemq.apache.org/ajax.html
• http://cometdaily.com/maturity.html

and new html5 way of it

• http://dev.w3.org/html5/websockets/

Hope these help.
