And to make sure, it's clear, $mypage in turnstep's
example would be the URL for your form. In other words,
if the URL for your form was:
http://www.mydomain.com/pages/myform.html
you would want to set $mypage equal to that.
Also, to make sure it exits gracefully if someone just
goes directly to the script, I would put the following
early on in it:
$errorURL = 'http://www.mydomain.com/mypage.html';
if (!defined $ENV{HTTP_REFERER}) {
print "Location: $errorURL\n\n";
exit;
}
This will send them back to $errorURL if they try to go
to the script directly rather than giving a possible 500 error.
