You have made this bold statement in several recent threads. It isn't true. If Google requests a URL and it returns "200 OK" then it is fair game for indexing.
I totally disagree, if that would be the case anybody could artificially generate duplicate content for any site he wanted. And there will be absolutely nothing you could do to filter it. Where you going to apply a redirect? To what parameter?
