I strongly doubt that Marcello is going to have the necessary warrants to
obtain that kind of information. My point to him is that the IP address
that he gets is not coming from the client. Your post, while technically
accurate, might have been easily misconstrued by someone who doesn't have
knowledge of how things work.

Boy, people in this group sure have become testy over the years!
