Applet/Servlet communication

How do I pass the data from the servlet to the applet without the request from the applet side ?
I tried to do it via sockets - it works, but this approach will not work in the protected networks where clients are behind the firewall.
Could anyone help me ?
Thanks

Try using the httpUrlConnection class. If I understand things correctly this class allows for socket communication even behind firewalls. Please post to tell me if this works for you.
