I have a customer intranet that now needs to be exposed to the internet. The
problem I now have is how to determine a users ip and then compare it to
another list that is internal versus external.

I know I can get the users IP using CGI variables, what I am not sure of is
what the best way to define the internal network(192.168.0.0) or external (
anything else) and redirect them to http or https. So basicly if your ip starts
with 192.168.???.*(I have multiple subnets that do and do not need access) then
you can use http. Anyhting else goes to https.

I would a appreciate any ideas or even better examples..

Thanks,
Chris
