Hi All:
Is there any one on the list who knows a lot about the interplay between proxying (mostly using apache), remote and local dns and computer names whose brain I could pick off-list?
The situation is we will likely be moving, and we need to do so without an interruption in our services. There will be some redundancy before the move, until all machines make the move.
What would be easiest at the new site is have our main agency DNS server point all of our server names to one server, and then proxy that over to where that service really resides. I have done a lot of proxying in Apache, but never where I had to make certain the the URL shown was correct, if the local machine that is running that service does not have the same name, the URL will still show the requested name (i.e. the person requests http://foo.agency.gov which gets points to http://junk.agency.gov which proxies over to a local machine called some other name, we still want the URL to show http://foo.agency.gov).
Even more, is it possible to have a local machine called foo.agency.gov with different IP address in our local DNS server from what is shown in the agency DNS server without everything getting bollixed up? This is because we have a lot of scripts and programs that use the computer name to move things internally between computers - there are issues where we don't want to go out of a DMZ say to resolve a name because that can cause access problems.
So if there is someone who's brain I could pick I sure would appreciate it.
-Roy
