 It shouldn't need to see plaintext though, should it? Whether a cache
 sends a stored or fresh copy depends upon other information: the
 Cache-Control, Expires, Content-Length, ETag, and similar headers.
 
 That said, I'm not totally sure either. Though the above is true for
 HTTP, there might be other constraints for HTTPS, and I'm not going to
 trawl for specifications now.
