Cometchat is it actually using comet?

So someone's selling a comet chat solution: http://www.cometchat.com/

But I think it might be a misnomer, because I don't think it ac开发者_如何学编程tually uses comet.

Can someone confirm whether or not it's actually a comet based chat, or just o' ajax.

Thanks.

Actually that depends

Do you use true Comet technology? By default CometChat is set to use smart-polling i.e. CometChat will poll depending on user activity. Taken from their website "If you activate our CometService, then CometChat will switch over to true Comet technology."

I suspect that you can also use true comet technology with cometchat in conjunction with ApeServer, BeaconPush or PusherApp, but you'd be best to email them directly to find out.
