Cache-Control:
header
which significantly improved the operation of both private
(browser) and shared (proxy) caches. This response header is
complex: it has many, many possible combinations of value. Some
common examples include:
Cache-Control: public
Authorization:
header.Cache-Control: private
Cache-Control: no-cache
no-store
directive is even more
restrictive.Cache-Control: max-age=3600
s-maxage
variant specifically
refers to proxy (shared) caches. Both of these are commonly
combined with re-validation options, to give (for example):Cache-Control: max-age=3600,
must-revalidate
