If digesting is going on, the requirement will likely be a little 
stronger -- the cache won't be able to combine headers from different 
responses, so the server should make sure that it always sends a 
complete set, or that it sends a digest of the set that the cache will 
choose to send, and perhaps the cache should detect if it gets 
out-of-date headers.
