Hallo Andy, sorry for the late reply, it was a busy day. This is exactly what i wanted to understand, many thanks!

Thanks, cheers, Stephan -- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/1838#issuecomment-1332962888 You are receiving this because you are subscribed to this thread.
