Yes, that's what I was looking at :) The '|' there is slightly confusing.

Yes, and it seems to work now, also without the "all.export /tas".

I want this, too ... but only for /tas path. Why is this not possible?

Mostly true ... only NFS is NOT dfs, each server there has separate files,
exported with different prefixes (/tas-5, /tas-3 ... ok, there is also /tas/
which serves a common namespace from two servers, but it is still not dfs).
What I want: :)
1. I have to distinct namespaces and two redirectors for those spaces.
2. Problem is they are both running on the same machine.
3. I want the redirector on the standard port number to blindly forward all
requests for the other namespace to another redirector on the same machine.
Does this makes sense now?
