I have a button in the header ("Search & Compare") linking to
"searchforextrafileds.php". There will be a header on the secure and
non-secure servers. When the one in the secure is clicked, I'd like the the
link to go to the non-secure server. If it's clicked in non-secure, it
should stay on that server.
Also, when the link is clicked, I'd like any osCommerce or PHP sessions to
be preserved. This is because someone may already have something in their
shopping cart when they decide to click that button. So, all sessions need
to be preserved.
