Max-age=0 from Proxy only

Hello All,

What is the best way to cache a file from an origin to a proxy server
(nginx) with a long max-age then change the max-age to 0 when the file
is
being downloaded from the Proxy.

If that is confusing hopefully this illustration will explain it better:

Thanks.

cache is not ment to be cached forever.
i think that you might can use an if statement that will make a
“location” decision by the source ip or some header.

in most of the proxies you can override the max-age by acls.

Setting s-maxage to a high value and while simultaneously fixing maxage
to 0 should do the job. Read the specs [1] for details.
