[TYPO3] RealURL automatic configuration but no realurl_autoconf.php?

[Robert Wuergler]

Hallo

RealURL:
I upgraded from 1.1.x to 1.2.1, leaving the default unchanged. According
to the manual a file typo3conf/realurl_autoconf.php should be generated
automatically, right?

After upgrading I did nothing but removing all entries in "Encode cache"
and "Decode cache".

Anything else to do after upgrading?

Thanks,
Robert
