I just had a little question regarding the way dnsdist handles queries to
its backends.

Use case here is for authoritative DNS, not DoH.

As far as my understanding goes (and backed up by a tcpdump test),
a UDP query on the frontend will result on a UDP query to the backend
server, and a TCP query on the frontend will result on a TCP query to the

Is there a way to force dnsdist to make UDP queries to the backend or is
this just not possible?
