Does the browser actually give up on the first address and go to
the second. I didn't think it did. The above really only gives you
load-balancing. If you want to do redundancy have a look at something
like fake or heartbeat. They do an ip take over when they see a host has
gone down.

Or if you really want to go to extremes have a look at something
like ultramonkey.
