i don't think you can do this all on Server-side. I once made things like that 
work with usual frames. I used Javascript in each page of the frameset to 
find out if the "parent" exists - and if not, redirect to the frameset which 
itself was a PHP script whom i told to load the current page in correct 
frames. I don't know if that's also posibile with iframes.

Anyway, you need to do two steps:

  1. You must be able to view the outer page with a parameter, which tells it
     what Site is to be viewed inside the iframe.

  2. Some sort of JavaScript wich redirects to the outer page. Tha JavaScript
     must live inside each site that might show up inside the iframe.
