Sorry for such a basic question, but I've Googled and can't find the answer anywhere. When a page reaches its expires lifetime and its cache expires, does W3TC automatically re-cache the page in the background, or does it not get cached again until a user visits that page again?
I'm trying to find the balancing point between speed (trying to always serve a cached page to visitors) and updated content. On a given page I have content (inventory) that updates throughout the day. If I leave the page cached for an long time, users and bots won't see the latest content . If the page cache expires too soon, some users will get served an un-cached (slower loading) page. (That is, unless W3TC re-caches automatically, hence the question.)
