Keeping secrets doesn't seem to matter in this case. Those who know
the technology well enough to implement something like this tend to
also know the market realities well enough not to make (as) boneheaded
decisions. It's kinda like why terrorists and nuclear scientists tend
not to be the same people.
Besides, there's a much better way. Have the restricted content
served by CGI or some other process that checks the HTTP_REFERER (typo
in RFC) header. If the person came to this page by any means other
than clicking a link on your site, this header will tell you, and your
server's code can simply redirect to your front page - or provide a
link to a new window, with no frames other than your own, with the
client besides basic HTML, is not required for this.)
