[Typo3] Using awstats-Extension and RealURL

[Tom Walter]

I am using RealURL and the awstats-Extension and both works basically fine.

My URLs contain transformed German "Umlaute" such as: 
http://www.mydomain.de/ueber-uns.html

Now I realized that the log generated (by the extension ?) looks like this:
... "GET /Startseite/_ber_uns--1.html HTTP/1.1" 200 13891 ...

How could I tell typo3 to log the RealURL (in this example just 
ueber-uns.html) without using the be-PATH (/Startseite/Über_uns) and 
without adding the page-id ??

Thanks !

Tom
