[Pdns-users] How to send NXDOMAIN using pipe backend?

[indranil.db]

That is what i am doing, sending only "END\n".
But then, i get another request which is a truncated one which is 
Jun 18 11:09:26 Query: 'Q com.my.domain.com IN SOA -1 127.0.0.1'
Note that the "abc" is missing.

At this point i send SOA record. Finally i send no data. Refer to the logs i
have mentioned earlier.
So the data flow:

> Jun 18 11:09:26 Query: 'Q abc.com.my.domain.com IN SOA -1 127.0.0.1'
-- Send only END\n
> Jun 18 11:09:26 Query: 'Q com.my.domain.com IN SOA -1 127.0.0.1'
-- Now send SOA
> Jun 18 11:09:26 Query: 'Q abc.com.my.domain.com IN NS -1 127.0.0.1'
-- Send only END\n
> Jun 18 11:09:26 Query: 'Q abc.com.my.domain.com IN ANY -1 127.0.0.1'
-- Send only END\n as there is no record available

If i do not send END at the start and instead send the SOA, then later send
no data then i get NOERROR.

So is it a way to tell PDNS in the first response only that no records
available so that i stops sending more requests and just treat NXDOMAIN?
