Uses inefficient cache policy on static assets
A long cache lifetime can speed up repeat visits to your page. Learn more. 17 assets found, all have only a 12h cache lifetime
Configure page resources to have long caching times so browser caches will retain them for longer. The cache duration of each resource URL can be specified by either 1) setting an
Expires
response header which specifies the point in time the response becomes stale such asExpires: Fri, 10 Aug 2019 20:00:00 GMT
or 2) adding amax-age
directive to theCache-Control
response header that specifies the number of seconds the response is valid for such asCache-Control: max-age=3600
for 1 hour. Ifmax-age
andExpires
are both used,max-age
takes priority. We recommend setting the cache time of page resources to at least 24 hours.
