Re: HTTP listening ports and URL questions

[Pete Helgren <pete@xxxxxxxxxx>]

I'd be dead without a reverse proxy.  I have a dozen or so internal 
addresses bound to the TCP interface and then one external IP.  I map 
that external address to one internal address and then that internal 
address is my one reverse proxy instance on Apache.  Then the dozen or 
so other Apache instances can be started and stopped and the "proxy" 
instance is just used to direct traffic back to all the server 
instances, some of which aren't even running on IBM i (Linux running 
Nagios is one example....)

It's so simple that I can add and drop hosts and domains on a regular 
basis as I experiment.
