[Unbound-users] Modifying query in C module

[Seetharaman Ramasubramani]

Yuri,
   Thanks for your input. Just this week I started implementing the code
changes based on the pointers you sent me earlier.
   I have concluded that the clean way to do proprietary meta data transfer
between client resolver and the unbound proxy is to place in an edns
option.


Thanks
Mani
