Partha- How about using the HTTP POST exchange?
1st applet gets the HTTPConnection from URL opens a PrintWriter (from the HTTPConnection OutputStream) writes to it closes ------------------------------------------------- Receiving applet opens HTTPConnection (from the receiving URL) opens a InputStream Readline on InputStream until no more closes --- -M ----- Original Message ----- From: "Partha Ranjan Das" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, February 13, 2003 9:34 AM Subject: Re: Pushing data to an Applet > Hi, > I think it is not possible without polling, because if the users are behind > proxy servers, then even if the server gets the remote addresses by means of > getRemoteAddr() or some other method, this address will only be that of the > proxy server and not the actual m/cs themselves.
