Help with Cisco Distributed Director and DNS subdomain

[Donald Pandori]

BIND 8.1.2 - HP-UX 10.20

I don't know if anyone has experience with these devices, but in a
nutshell, they are able to load balance based on routing tables.  We are
going to use them for load balancing across web proxy servers.

According to the docs, a subdomain http-proxy.my.domain.com needs to be
setup under the my.domain.com domain with the Distributed Director being
the master server for that subdomain. 

The idea is that in a person's browser they would actually point to the
subdomain as their proxy and the Director will take care of getting the IP
address to use as the proxy server.

The example that Cisco gives is this:

http-proxy.my.domain.com	in	NS dd.my.domain.com
dd.my.domain.com	in	A	1.2.3.4


They say that if you do an nslookup a different address should be given
back each time.

Any ideas?  I have looked at trying to set up a zone for that, but the
Directors don't support zone transfers so that would be pointless.  I'd
like to set up some sort of forward zone that just jumps to the Director
automatically.

Thanks.
