Something on the server side of the connection would have to access the socket in order to see if the other end is still alive, and the request processing thread has control of the socket, so other server code can't really presume to use it. > or at least provide them the opportunity to cooperatively > abort themselves when discovering an aborted connection - > other than by having them attempt to write to the socket? There is a Socket.isOutputShutdown() method that /might/ indicate that the client sent an RST, but the exact JRE implementation may well be platform-specific. Failing that, writing to the socket is the only way I know of to be sure if the client is still listening (and even that's not a guarantee). - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
