Feh nocache: minimize caching effects

The cachestill stores the response, enablingconditional requests withETag or Last-Modified. The max-age directive declares the number of secondsthe response remains fresh after generation. A request carrying no-cache requires the cache tovalidate the stored response with theorigin before serving the copy. The cache returns thestored copy only if the response will stay fresh forthe additional period. The max-stale directive signals acceptance of aresponse whose Age has exceeded the freshnesslifetime by up to the given number of seconds. You can click on each one and open the Headers tab to see what response headers, including cache-control, were sent by the server.

The no-store directive prevents any cache fromstoring the response. Private browser caches ignore s-maxage andfall back to max-age. This directive is useful when an originserver is temporarily unreachable and a slightly staleresponse is acceptable. When no Cache-Control header is present,caches apply heuristic freshness.

Use max-age=0 to force revalidation​

Cachesskip conditional requests forimmutable resources, eliminating revalidation roundtrips for assets like versioned JavaScript bundles orfingerprinted images.
