Hmm. So, when people who hate javascript visit, they have to re-set
their browser, and then re-re-set it on leaving. Are you sure that you
really _need_ to require your visitors to use javascript? I once did
banking at a place that required that, and it irritated the hell out of me.

Well, I don't know fully what the questions are, but yes, other things
being equal, a JS check will usually work.

Well, you could just generate a page to re-ask the problem question with
the same script, if you wanted.

Doesn't always work, even with JS enabled. You'll also have to require
your subscribers to use their browser's history list, which some people
disable, for instance with security software.

As long as you can already program some in Perl, just do it right and
generate a page with a script to get the information needed. All this
jumping around in javascript sounds a bit kludgy for my taste, but it's
your page.
