Use long caching times #358

Closed ghost closed 5 years ago

ghost commented 6 years ago

A long cache lifetime can speed up repeat visits to your page.

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 as Expires: Fri, 10 Aug 2019 20:00:00 GMT or 2) adding a max-age directive to the Cache-Control response header that specifies the number of seconds the response is valid for such as Cache-Control: max-age=3600 for 1 hour. If max-age and Expires are both used, max-age takes priority. We recommend setting the cache time of page resources to at least 24 hours.

Hello,

I think it's done. Doesn't it?

Regards,

@alemuro this is what I just measured using google lighthouse

6h for images is really short.

So it doesn't seem to be fixed for me.
