Netscape has its own, internal address cache (so that when a page contains
image and/or frame links to other pages on the same server, it doesn't have
to do zillions of DNS lookups). I think it caches addresses for 5 minutes
I'm happy to learn that it does failover. Given that it does, it's not too
surprising that the address it caches is the one that it actually used.
