Hello, All! It's a little bit offtopic but relates to an ICS-based software, and I suppose ICS gooroos may shed some light on this.
Imagine you have a public web-server (runs on Windows 2003). From time to time, some strange client software opens a connection(s) on the server but never issues a http request. Such connections may stay open quite a while, even longer than 10 minutes which is equal or greater than usual timeout for sockets (to my belief). That happens several times a day. There is no any info about these clients except for ip-addresses. The only thing that can been deduced from the log is that the same ip-addresses are used (in other connections) by clients with IE browsers (if we can believe given values for the Agent header). Does anyone know what this means? Why don't the dummy sockets get always closed by server OS upon a timeout? I'd suppose that there should be the same timeout for all such dummy connections, but they live different times, even for days, without data transfer, waiting until I kill them explicitly in backend UI. Thanks in advance. Best wishes, Stanislav Korotky. -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
