The expiry mechanism can be relatively easily circumvented, but
nonetheless most of the time it isn't. If the cache *by default*
passes back statistics to servers, then most of the time it will be
left to behave in that way. You can't enforce *anything* with the
protocol :) but you if you make it possible, you take a step forward
from the current situation.
