This has sat for a while. I tried to come up with a minimal change...

Proposal - replace:

> These are combined as
> 
> corrected_initial_age = max(apparent_age, corrected_age_value);

with:

> These SHOULD be combined as
> 
> corrected_initial_age = max(apparent_age, corrected_age_value);
> 
> unless the cache is confident in the value of the Age header (e.g., because there are no HTTP/1.0 hops in the Via header), in which case the corrected_age_value MAY be used as the corrected_initial_age.

Thoughts?
