filter: do not modify deniedurl cgi parameter

Keep the modifications (which are needed for key lookup) inside the
lookup routine. This includes e.g. lower casing the URL. This way
can pass the exact original request string to our block page script.
This also changes the way 'www123.' is stripped from the request.
