https://tools.ietf.org/html/rfc7234#section-5.1 :

{noformat}
   The presence of an Age header field implies that the response was not
   generated or validated by the origin server for this request.
   However, lack of an Age header field does not imply the origin was
   contacted, since the response might have been received from an
   HTTP/1.0 cache that does not implement Age.

https://tools.ietf.org/html/rfc7234#section-5.1 :

{noformat}
  The "Age" header field conveys the sender's estimate of the amount of
   time since the response was generated or successfully validated at
   the origin server.  Age values are calculated as specified in
   Section 4.2.3.

> You can sometimes see Ages of 0,1,2,etc.. - the time it took to process a request - for requests not served from cache.  Causes confusion.
