Hiya, I am a little confused with this URL ( http://$sum(7,18,- 9.4).x42.com/ ) . I was wondering whether any of the guys on this channel had any idea on how something like this can be done. I think that there is some DNS trickery taking place in the background. Any clues ? Regards, Al. Sent via Deja.com http://www.deja.com/ Before you buy.
