It's not hard in Java (Socket.getRemoteSocketAddress() or Socket.isConnected() should work), but there's nothing in the servlet spec that allows a servlet thread to obtain for that information. Ideally, the container (Tomcat) would asynchronously monitor the socket status and set some flag in the Request object for the webapp code to examine at its leisure. Might also be able to implement this with a new form of listener. I haven't looked at the Servlet 3 spec to see if anything is in there for this rather common problem. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
