I don't think that would work. It is easy to obtain this new link and
then make a deep-link on the other site like

<a href="http://mypmwikisite.com/thisgroup/B?show=1">Great Downloads</a>

which would be accepted.

I was thinking that cookies might help. Page A sets a cookie which is
read by page B. If the cookie is missing, B redirects to A.
I have come as close to HttpVariables, but I find the docs not too clear...

Or what about something like:
--------code-----------
 *Page A:*
 Instructions

 [[B?show={$Date} | Continue…]]

 *Page B:*
 (:if !request show {$Date}:) (:redirect A quiet=1:) (:ifend:)
 Links...
---------/code-------------
If there is something like {$Date} in PMwiki, that would create a link
that changes every day!
Would that work?
