I am not sure I quite understand why it doesn't work and a resolver is needed.  If I do a dig it answers to the proper IP.  It stands to reason that I should be able to access that server through a web browser, and it cannot.  What is a resolver going to tell my system that it already doesn't know ?

I'm not sure off hand which address linux would return in this case. (How would it know when to return which one?) What makes this work is that one resolver (your local resolver) is used when connected to the LAN which returns the LAN address corresponding to the name, and a different resolver (internet authoritative dns) is used when connected to the WAN. A firewall such as IPCop can be used as a local resolver to provide the local addresses (recommended method). This can also be implemented in a single bind host using the split horizon feature, but that's a bit tricky. --
