Joe, I have thought about this but for every connected user one thread will be blocked and if I get say 5000 users on my site then will the IIS + Tomcat combination will be able to handle 5000 concurrent threads. I doubt!!!

Even if there is no data change, servlet sends something back periodically to keep the original connection alive. This does mean you tie down one connection and thread on the server side for each client applet. And if the applet lost the connection, it can re-establish another one. I have not done this myself so I don't know what other issues this may cause. regards, -Joe -----Original Message----- From: Bhushan Bhangale [mailto:[EMAIL PROTECTED]] Sent: Friday, February 14, 2003 1:07 AM To: [EMAIL PROTECTED] Subject: Re: Pushing data to an Applet Dear Uwe, I read it but it uses RMI and Socket which is not possible for me as the users who will browse the applet will be outside the firewall.

It talks to server via Applet to Servlet Communication. There is one application running at the server side, which processes some order. Now the functionality which I have to build is that the application should be able to push orders to the applets, so that the users who are currently watching the applet should be able to see the latest data automatically without sendinga request. I searched on web but couldn't find anything as to how can I push data to all the connected applets of the site. The solution which I thought is the applet will poll the server after every say 1 minute to check if there is any new to show. But suppose the number of user is more and there is nothing new to show, the applets will unnecessary making the request to the server. I can't use Socket connection or RMI as the site will browsed outside the firewall. Is there any way by which I can push data from server to applets, so that when ever new thing will come server will make connection with applets and push data thereby using network only when needed. Unlike in polling the network is used unnecessarily.
