[dnsdist] Modifying requests

[Steve Freegard]

Hello,

In Packet Policies, it states that each packet can be "Modified and 
forwarded to a downstream and be modified back".

But I can't work out how to do this and the docs don't appear to give 
any examples - what I would like to do is remove a label from the qname 
before forwarding to a pool.

Anyone have any pointers as to how to do this?

Kind regards,
Steve.
