It may have been set some pages ago, via a POST (and now via a SESSION).
It may have been set on the previous page via a POST.
It may be in the URL in a deep-link, so via a GET.
And it may be required in consequent pages.
I need to cover all possibilities, because they all occur at some time
or other...
