Hi Wilko, since I have been able to set up my servers, I tried the error on redir. In my opinion it works, I have a redirector on noric02 and a data server on noric04, and this is what I get: 050621 16:32:18 9113 Xrd: ReadRaw: Disconnection reported onnoric04.slac.stanford.edu:1094 050621 16:32:18 9113 Xrd: PhyConnection: Disconnecting socket... 050621 16:32:18 9113 Xrd: XrdClientMessage::ReadRaw: Error reading 8 bytes. 050621 16:32:18 9113 Xrd: CheckAutoTerm: Self-Cancelling reader thread. 050621 16:32:18 9113 Xrd: SocketReaderThread: Reader Thread exiting. 050621 16:32:18 001 Xrd: ClientSock::SendRaw: Disconnection detected writing 500000 bytes to socket 4 (server[noric04.slac.stanford.edu:1094]).

So I think we have to clarify ourselves. Instead, due to the new commits to XrdClientUrl, it seems that the session stuff is (again!) broken, at least through redirections. I'll check better.
