Not currently a part of DNS.  Try putting a load balancer such as a
BigIP box in front of your Web servers.  You can buy a BigIP box from
F5 Labs, or (I am told reliably) you can buy a PC from Dell and get it
delivered with F5 software on it.  Fairly reliable - it is BSD/OS
based.

There are experimental schemes to do this within DNS, but they are not
in use in your average browser yet.
