The fact that headers are not merged is one of the main reasons 
why proxy_cache_revalidate is not switched on by default.

As for the headers specifically mentioned in this thread:

- nginx do update Date header (actually, this is the only header 
  updated);

- nginx do not support Age header at all, see 
  https://trac.nginx.org/nginx/ticket/146.
