Not one, you must have them for every domain. This is clearly stated in the manual. Otherwise RealURl will have to make many extra queries to find that rootpage_id every time when page is visited.

If have a path like this: http://example.com/path/to/page, RealURL must know where to start searching for the final page. It must start with domain (example.com). You can either hint the rootpage_id or force RealURL to make a query to search for domain. Sometimes it is not a single query as you can think. So, if you do not specify rootpage_id, you force extra queries *at every visit* to the web site.

It works if you do not specify rootpage_id but you pay for it by performance decrease.
