Is there a way to keep forum.example.com in the adress bar and only that? So you can not see the urls of the pages, but just forum.example.com? I tried with an iframe, but it does not work. The forum itself is on www.example2.com
<FRAME SRC="http://www.yyyyyyyy.nl/index.php?categories/wwwwwww.18/" NORESIZE>

The domain name is setup in Plesk as an inframe redirect.
