Forward Unknown Lookups

Forgive me if this has been asked before -
I'm trying to set up bind to have A records for a zone, but forward
requests for that zone to another known server if lookups fail.
For example, on my server, I would create a record for the zone
server IN A 10.0.1.1
But I also want requests for example.com to be forwarded to another
DNS server if mine can't resolve it. So, in the above example, I
would like my server to resolve 'server.example.com', but if a
requests for another example.com name comes in, it gets forwarder. A
lookup for 'www.example.com' which my server would not know about
would get forwarded.
What I'm trying to do is have some clients be able to lookup entries
on my server (the would be using my server as their DNS server), and
have those lookups fall through to a 'more authoritative' DNS server
if I can't resolve it. Sort of like a caching DNS server, but the
server would be able to provide lookups on certain records not
available in the forwarder server.
Thanks in advance!
