[TYPO3] RealUrl and two websites in one database

[Michael H.E. Roth]

Hello,

I'm having similar problems... I do have a couple of Websites all with 
the same Template- and Page-Structure just with different content.
  No matter what page I call via it's realurl-name, I always get the 
content of the "root"-page of that domain - if I call it with it's 
page-id (domain-a.com/?id=x) I get the correct page...

done that!

Where, and how exactly do I have to set rootUID (in the setup or in the 
constants)?

It would be nice it you could post a "complete" and working example 
(maybe even as comment to the realurl-docs...)

Thanks in advance
