Appreciate all the input! Those things were already part of my list
that are mentioned in this email.

What I was trying to point was that we are really in restrictive env
where server A can't be changed and 3rd party may not agree to change.
So I was wondering if there is something like caching on Apache
servers or something similar that can help. So if user A with id "A"
comes to site 1 and if that user is actually supposed to be in site 2
then redirect. Or may be some better solution on similar lines.
