With the Pro version, I’m getting familiar with CloudFlare cache, and I’m testing a directory of my website (* myserver.com/dir/*) with a Page Rule with the following settings:
- Browser Cache TTL: a day
- Always Online: On
- Cache Level: Cache Everything
- Edge Cache TTL: a month
I’ve just tested with ‘curl’ the cache headers of one of my webpages, which I tested yesterday with ‘curl’ with my Linux laptop:
- Cache-Control: max-age=86400
- Expires: Wed, 11 Nov 2020 11:38:42 GMT
- Strict-Transport-Security: max-age=31536000; includeSubDomains; preload
- CF-Cache-Status: HIT
- Age: 87441
I do not understand why the ‘Expires’ value is of yesterday. According to Mozilla (https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Expires), this means that the response “is considered stale”.
Any tip to understand this is welcome. Thank you.
