As I understand it, Wendy is considering the case of a multi-homed server. She wants to record the IP address on which we received the datagram so that she knows which locks to invalidate in the case of a migration of that particular IP address onto another server. My point is that she won't get that information if the socket is bound to INADDR_ANY, as would be the case for a UDP socket. Cheers, Trond Using Tomcat but need to do more?
