Question about APO

There are 2 primary things APO does:

  1. Cloudflare doesn’t cache html content by default. APO essentially handles cache rules so that html files can be cached without user A seeing the content of user b.
  2. The plugin detects when you make changes, like posting new content, and automatically purges the affected pages from Cloudflare’s cache so that visitor’s see the new content immediately.

I realize it caches content in a specific way. But what are its caching rules, what optimizations are made? I don’t see it change anything the Cloudflare cache settings, so that’s why I’m asking. In case it matters, I’m a web server admin, backend web code developer, WP and WC backend dev expert, been doing Internet dev work for nearly 30 years. So I prefer some more detailed technical info.

It looks there’s a bit more detailed info at this page:
