"Server Push" relation in IE

[InfernoPyro]

I know that "server push" works in NN, but when I try it in IE it obviously doesn't work. I recently went to

http://my.bzflag.org/irc/irc.cgi,

and has some kind of very similar technology that works in IE. Can someone please tell me what it is, and even better tell me how to use it and give me some examples.

Thanks, Inferno
