Query on forwarding in Bind 9.2.x

But, it does work in BIND 4.X versions. So, I was wondering whether it's
a (compatibility) defect or misconfiguration.
In Bind 4.x, a server configured with  forwarding is able to serve
queries on both child domains and other domains. But, in Bind 9.2.x (may
be in 9.3.0 also), it is not able to serve requests on child domains, if
it has forwarders configured.

Probably due to the fact that the name server has received a recursive

query (query coming from a client resolver) for data that resides in a

zone for which the name server is not authoritative.  With 'forwarding'

configured this behavior is normal.  However, if another name server
to ask, it would get the referral and follow the delegation.  You may
to consider not using forwarding...
