Requery on RR expiration automatically

[John Morrison]

Hello All,

Is there any mechanism that can be implemented so bind will requery for =
any records it has in its cache automatically upon ttl expiration.

The problem is that a certain piece of software has a caching stub =
resolver built in. This stub is horribly erroneous. One error is =
improperly caching NXDOMAIN for a record where the stub simply timed out =
the query. Once in cache it is never retried until the server is =
restarted.

What i would like to do is have bind cache all the domains that our stub =
will ask for, and always have a cached version of the record unless it =
really doesn't exist.

Thanks,
John
