I want to block access to internal websites via the proxy. I want to do this on the proxy itself, but I'd like to show the user a proper error message like: "Don't access the internal net by means of the proxy". Is that possible? -- Ralf Hildebrandt (i.A. des IT-Zentrums) Ralf.Hildebrandt@xxxxxxxxxx Charite - Universitätsmedizin Berlin Tel. +49 (0)30-450 570-155 Gemeinsame Einrichtung von FU- und HU-Berlin Fax. +49 (0)30-450 570-962 IT-Zentrum Standort CBF send no mail to spamtrap@xxxxxxxxxx
