No - they see the IP address oft that host which runs (among other services) the service/program "squid". > Maybe you want to check the http headers HTTP_CLIENT_IP > or HTTP_X_FORWARDED_FOR... That's the apache part (or what webserver may run on that host). And the webserver only reads this address, it cannot change it. Viele Gruesse! Helmut
