There was some discussion of forcing cookies, but the author didn't want
to limit his users, so...

How about doing something like this:

// See if the user agent is Googlebot
$isGoogle = stripos($_SERVER['HTTP_USER_AGENT'], 'Googlebot');

// If it is, use ini_set to only allow cookies for the session variable
if ($isGoogle !== false) {
ini_set('session.use_only_cookies', '1');
}
