in web applications, some cases we want to send some data from server side to client side (web browser) needn't the client send request. ButI can't know how to do?.

Example, I develop a web based chat application. in that, I have 2 persons A, B. A send data to B via server side, and then server side send the data to A. Assume that, A connected Server side before.

P/S: By the way, could you show me ideas to build a web based chat instead of.

Thank you so much !

I don't think you can do that unless you have an applet!

if you have applet, then you open a socket conn from applet and do the back/forth communication.

other wise, you need to periodically make javascript to check the server to get any update.

Thank you for your reply.
Do you know, how gmail web chat do ?

Gmail web chat is a good example for this. as you know, when our partner types some chars, the web client show : "xxx typing....".

It's not good to use javascript to check periodically.

u could use AJAX, and have the client check the server on some fixed interval (how gmail works).. but there is no way for the server to just send data to a client, without the client 1st requesting the information
