Absolutely agreed... but I have seen funkiness if you have multiple external 
IP addresses on an interface (of course... this is just waving in the wind as 
Doug didn;t give us specifics). With the "Listen [<ip>:]<port>" argument in 
httpd.conf you can tell Apache to listen to everything on a port of any 
address (the default), or specific address:port combinations... I have seen a 
weird case before on a machine that had multiple IPv4 addresses on an 
interface, was set "Listen 80", but would only respond to one of the two 
addresses on the interface. Restarting Apache didn;t seem to help.. .a reboot 
of the machine magically fixed it.
