Hi Faisal, Many thanks for the response, very helpful. Luckily the Client IP is the one that I'm trying to set, so it looks like %REMOTE_IP% is the special variable that I want. I'll go find the definitions of %REMOTE_IP% in the documentation to ensure that it's what we need. However, we need to upgrade anyway, and this is just fuel to the upgrade fire.. Many thanks, Paul
