How can I allow/deny a layer if I browse the map from Intranet/Internet?

[Camden Daily]

I would strongly suggest using mapscript to get the desired results.
With mapscript, it would be quite simple to just check the ip of the
person requesting the page and set different layers to be turned off
accordingly.

If you're going to be confined to using the cgi-bin mapserver, you
might look into mod_suexec for apache.  You can use it to define a
different user/group that cgi apps will be run as for different
virtual hosts.  Then, you could set your layers with permissions that
only make them available for the specific user or group that should
have access.
