I was thinking to deny access indirectly to all those site visitors who have their IP suppressed by Norton or similar tools - for the simple reason that without IP it is more difficult to track hackers and if someone wants to read my pages I love to know from where he is. unless there is a reason NOT to do so - if then please explain briefly - I would want redirect all empty remote host IP requests to a page similar to /missing.html (empty_client_IP.html ) principle for 404 instead of just blocking. anyone knows howto or has done so ?
