Cache expiring overnight

    I’m using WPSC to set s_maxage, and the Cloudflare page rule has no EdgeCacheTTL setting. All looks good in the header. When I set this to 120 in WPSC, the cache expires in 120s.

    When I set s_maxage in WPSC to one year (or month, or week), half of my Cloudflare page caches expires overnight. I believe I checked the WPSC log about this time, but didn’t see any activity.

    Repeating this with the WPSC preloader turned off, nothing changed.

    I then deactivated WPSC, set s_maxage directly to one week, confirmed the response headers were correct, and tried it overnight.

    It worked fine.

    While the WPSC page cache may help in reloading the Cloudflare cache, it’s still much slower than having that cache stay valid. Most options are set to the default, and this is just a very simple new blog. It currently has very little traffic.

    I just started WPSC again, leaving everything in defaults. Except for increasing the max log file size to 20MB.

    I like everything else about WPSC, but I’m out of ideas on fixing this.

    Update 2/11/21
    For the past several weeks, every morning after WPSC has been running I found half the Cloudflare cache expired. This morning, my Cloudflare cache was intact.

    Other than deactivate/activate on WPSC, the only change I can see was my turning on the Cloudflare WP plugin, as that appeared to be needed for the fallback cache to work, I’ll assume for now it’s lack also caused this issue. I guess I’ll have to wait a few days to find that out for sure, before marking this item.

    The 2nd day working confirms it. WPSC requires the WP Cloudflare plugin to work properly.

    That makes sense if you’re using Cloudflare. Things get very complicated with more than one method of page caching.
