As I understood Hassan, he wanted to be able to edit the META tags in the frameset definition. If he could, then the "www.mysite.com" would have useful META information, even though all the actual content is piped through the frame from the personal web server.
However, the frame method doesn't have any options, so there's no way to actually do this. That's also what I meant in my earlier reply. Bottom line is, if you let Dreamhost "redirect" to your personal web server, then you can't specify META information anywhere else than in the pages of your personal web server - not in the Dreamhost frame. Correct me if I'm wrong.
