Surely you are joking?? Don't they use DHCP for dishing out addresses? I guess AOL users just have to do without https during peak hours :-) > Further, large corporate users will ALL appear as a single IP address. Yes, that's assuming they're using NAT - which many small and large entities will be, I agree. In such cases, if the session id _is_ somehow tied to the IP-address, any attempt to hijack the session from outside the NAT'ed network will fail. >> Regardless, I did some googling and read a bit about session >> hijacking and such.

But what I said was that _maybe_ 0.00X% have REFERER switched off - and 0.001% of 1billion is 10.000 people. I can live with that. > If you have even a few thousand visitors, you are likely getting at > least a few that have no REFERER... Like I said, I can live with that. If people are that paranoid, they shouldn't be on the internet at all, IMHO. /Per Jessen, Zürich -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
