I am hoping someone can help me out with this.  Maybe I just can't see how it would 
work......but anyways we have apps that are going to be accessible outside our 
firewall.  We currently have a set-up like this.

Webserver is in dmz with the  ports http/https accessible to the outside world.  CF 
code is kept on this server.  Database is completely inside the firewall.  The 
firewall is configured to only allow communitcation from the webserver IP to the SQL 
IP over a sql port.  There are voices around here that want to see a 3rd layer or an 
app server inbetween.  I can't visualize how this would work?  I think I may just need 
someone to help me visualize it.  Anyways taking into consideration that the webserver 
software is all patched up and tighened down, the code has been analized to ensure 
that there are no holes will adding the extra layer really do any good?

Thanks

Mike
