OK, right now a server sending "no-cache" means "don't-cache" and a client
sending "no-cache" means "not-cached" or "not-from-cache". The current
use of "no-cache" doesn't 'feel' very symetric which may be why, in part,  
there is so much confusion. Would the use of slightly different terms
be possible *and* make any difference? ("dont-cache" and "not-cached").

I finally understand why reload != no-cache and I've convinced myself,
at least for the moement that we don't need reload ... I plan to review
draft wording as it should appear clearly in the text by way of example
and it may ...
