[TYPO3-english] realurl: is rootpage_id necessary?

[Loek Hilgersom]

Hi all,

On a multi-domain site I discovered that the realurl configuration for 
rootpage_id was not done correctly in realurl_conf.php, but still everything 
seems to work fine.

I tried e.g. to access sub1.domain.com/news and sub2.domain.com/news and both 
deliver the right - different - page.

realurl_conf.php has been done manually and it makes use of the 
tx_realurl_advanced script [1], so I would expect such requests to fail without 
the rootpage_id's set (e.g. both delivering the same page, or generating an 
error because of conflicting path names), but all appears to work fine.

So my question is, do I really need that setting, and if yes, how could I 
enforce a failure to test whether it has been set or not?

Thanks!
Loek
