Chat server push technology

[xpblueScreenOfDeath]

How are web base chat program done without the client browser refreshing or pulling for information on a timed interval? In other words, how dones the server sending the client browser information without the client browser first requesting for the information.

The chat programs I've seen that work in a browser window are Java applets (not Javascript), and they maintain a connection to the server on their own.

AJAX can also be put to good use for chat programs to update the conversation without refreshing the page.

Hope this helps,

The web based chat solution I use polls the server every X seconds using ajax.
