Yes. All good so far. And when you run the same script via the other
domain...?

Now I'm totally confused. Two of us have suggested the relevant variables
to you, a combination of which should tell you everything you need to
know about the server name, the request URI and the real script path,
yet this isn't enough.

Somewhere either you've not explained yourself sufficiently or one of
the three of us has misunderstood. Same net effect.
