Jonathan Moore 55742a46e1 Minor enhancement to stale-while-revalidate (RFC5861) handling; now we can also
serve stale 304s (Not Modified) while asynchronously revalidating. Prior to this,
we were always returning a stale 200 response regardless of whether the incoming
request was conditional or not. The old behavior was not incorrect, but this is
better.
