What do you mean by saying that "Prefetch does not cause named to ignore
I think in my case, I have set the preftch option like this:
prefetch 2 9;
This will enable the prefetching for all of the entries with the TTL larger
that 2 seconds, (in my case, the TTL is 60 seconds, so the prefetch will be
enabled for this entry). The digit 9 triggering condition for doing the
prefetching. In my case, it should mean that when 51 seconds elapsed for
the entry, i.e., 9 = 60 - 51, the bind will prefetching the record, and
then the record will have a full TTL, i.e., 60 seconds for this case again.
Am I wrong about the meaning of the prefetching function of bind or not?
