A server could maintain backpointers on target >resources, but not attempt to insure that references are always valid. I'd go further and say that whether or not a server maintains backpointers should have no impact on the protocol used by the client to obtain information on backpointers from the server. How it is implemented by the server does not in any way change the semantics exchanged between the server and client. ....Roy
