Jeffrey Mogul: >To wit: the spec >explicitly allows your caches to ignore the expiration times This is only allowed if a Warning is added, I believe. I have always had doubts about whether cache implementers would want to implement Jeff's Age calculation algorithm without any changes. I tried a number of times to get Jeff to add a clause allowing cache implementers to implement any other algorithm which would not increase the chance that a stale response was returned. I never succeeded. Thus we end up with a spec requiring implementation of an algorithm that is obviously sub-optimal, and much move vulnerable to desynchronized clocks than it needs to be. But I don't think it is productive to update the 1.1 draft and resubmit it for proposed standard again. It will be interesting to see if certain parts of the draft never get implemented by cache implementers. If that is the case, I believe that the IETF process allows us to cut these parts when going from proposed to RFC. > -Jeff Koen.
