Hello All,

My apologies if this has been asked before, but I have done extensive Googling 
and I can't find it if it has!

What we're doing is using a Reverse Proxy setup to redirect a local request to 
another local URL:

ProxyPass /path/morePath/info http://localhost:7000/morePath/info retry=0 ttl=10
ProxyPass /path/morePath ws://localhost:7000/morePath retry=0 ttl=10
ProxyPass /path/ http://localhost:7000/ retry=0 ttl=10

That works MOST of the time. The problem we're seeing is this: If we try to 
pre-configure a system that is set up for DHCP but has no network connection 
(pre-configuring on a bench) and thus no IP address, we're having trouble with 
the redirect. BUT if I change the above to the following:

ProxyPass /path/morePath/info http://0.0.0.0:7000/morePath/info retry=0 ttl=10
ProxyPass /path/morePath ws://0.0.0.0:7000/morePath retry=0 ttl=10
ProxyPass /path/ http://0.0.0.0:7000/ retry=0 ttl=10

Then it works fine.

So my question is: what's the difference here? What exactly does mod_proxy do 
with the address 0.0.0.0, and why doesn't "localhost" work?

Thanks for whatever help you can give!
