Hi Pete, >>The reason why I'am asking all this is that we are working on a xrootd >>mover in dCache. Currently, the client connects first to a known xrootd >>door which then causes the redirect towards a xrootd mover, from where >>the file transfer is performed.

What type of information do you intended to pass? (Sorry if > I missed this earlier in this thread.) The Poolmanager inside dCache selects the best data pool (which causes that pool to create a xrootd-enabled mover instance for that specific file transfer). Passing some piece of information(e.g. the pnfsid) during the redirect would allow the mover to verify the client request. Best regards, Martin
