[Pdns-users] Retry NXDOMAIN with a secondary forwarder

[Richard Connon]

Is it possible through lua scripting or otherwise to configure powerdns 
to look NXDOMAIN responses up in a second forwarder before returning 
NXDOMAIN.
To clarify I'd like it to go something like:

lookup name in NS1
if found in NS1:
     return NS1 result
else:
     lookup name in NS2
     return NS2 result
