I got chatting at a Christmas party with the owner of a web site 
who has twice changed ISPs because his site got hacked.  He's about 
given up on ISPs to provide protection, and is looking to set up his 
own server and protect it.
  I keep seeing recommendations that HTTP servers should be in the 
DMZ, but I'm not clear on WHY.  Is this, perhaps, to protect the 
machines on the internal net from a compromised HTTP server?  In this 
case, there wouldn't *be* any "rest" to protect.
  My inclination is to suggest a proxy machine as firewall, supplied 
with content from the "real" server behind it.  But maybe there's a 
flaw to this that I haven't quite grasped?
