Bur Mongo db is not seen at all from pdns , is hidden by my code used by the remote backend via http. My app is the one acceding mongo and responding to this http to remote backend.
The question was how to avoid this big loop of questions since the first one has a correct answer, and zone information was answered before the naptr query, I want only one query if possible.
