All this TTL talk makes me think.
Why not have two ttls - a 'must-recheck' (does not expire the record but forces a recheck; updates record if server replies & serial has incremented) and a 'must-delete' (cache will be stale at this point)?
If clients can't get one TTL correct what makes you think they will get a more complicated two TTL system correct? -- Eitan Adler
