Hoi,
A user of the nl:wikipedia who had the misfortune to be blocked on a proxy server,
mentioned that many providers send a HTTP_X_FORWARDED_FOR header along. This she said
could easily be retrieved using PHP with the variable
$_SERVER["HTTP_X_FORWARDED_FOR"]. Now when this is true, it makes excellent
sense to use this IP-adress for the registration of contributions but also for the use of
blocking specific IP numbers.
I have no idea if our software uses this or not. I thought this a great idea so I move
this remark to you in the hope that we can enhance our software and make our anti vandal
solutions more accurate.
Thanks,
GerardM
