<p>If the isHeuristicallyCacheable parameter is true, however, the current response has been marked
as cacheable in a public (shared) cache, but did not provide an explicit lifetime that would serve
as an upper bound. In this case, we can proceed and possibly keep the directive on the final response.</p>
