I'm assuming that you actually mean you've added the second line above with no 
comment # at the start (otherwise of course it does nothing), however are you 
sure this is supposed to work with the ! negation in the ACL?

Do you get any warnings when starting Squid (when it reads squid.conf), and 
what appears in your access.log when you attempt to connect to a URL which you 
expect to trigger these rules?

The format of the line above should be:
	OK status=301 url="http://www.freenet.de"

Surely the above line should just be:
	print STDOUT "OK\n"

See http://www.squid-cache.org/Doc/config/url_rewrite_program/ for syntax 
details.
