Yah, true. The recursive server is free to not accept responses, to evict cache entries early, to <gulp> stretch TTL, etc. An authoritative name server can provide information so that the recursive server that the client is using can populate its cache if wants to...? W -- I don't think the execution is relevant when it was obviously a bad idea in the first place. This is like putting rabid weasels in your pants, and later expressing regret at having chosen those particular rabid weasels and that pair of pants. ---maf _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
