What is never cached
Whatever the settings say:
- Anyone who is signed in.
- Anything submitted with a form — a POST is never a cache hit.
- The admin, the login screen, the REST API and cron.
- Pages that set a cookie, or that send
Cache-Control: no-storeorprivate. - Password-protected posts, previews and the customiser.
- With WooCommerce: the basket, the checkout, account pages, and every page for anyone with something in their basket.
- With Easy Digital Downloads: the checkout and the receipt pages.
Anything that says "not cached" in Diagnostics will name the exact rule.
