Something like:
If there isn't a session, start one and redirect to the same page WITH the
session id, otherwise just continue the session.
In theory, you should always get a session ID in the URL of startpage.php.
But I can't stress enough, this is all theory -- the code hasn't been tested
at all... nor particularly thought through :)
startpage.php:
<? // untested code
if(!isset(session_id()))
{
session_start();
header("Location: startpage.php?PHPSESSID=".session_id())
}
else
{
session_start();
}
?>
<HTML>
...
</HTML>
