[Pdns-dev] passing original QTYPE to the backend

[Zane Thomas]

Benjamin,

DNSPacket * which is passed in to the lookup method can be used to
determine what the original query type was. I very much needed to use
the packet pointer in order to select which records of a set which, in
the database my backend interfaces too, are as a set non-rfc
compliant. My approach was to look a  the packet query type and return
to pdns only those records it needs to answer the query.
