RFC 1035 specifies in chapter 6.1.3. that requests served from a cache should return a TTL which has been decremented by the amount of seconds in cache, i.e. the TTL "counts down" in the cache. Therefore I consider any caching nameservers that do not do this broken. Are there a significant amount of such servers out there? Though I agree on most of the other points. > -- > To UNSUBSCRIBE, email to [EMAIL PROTECTED] > with a subject of "unsubscribe". Trouble?
