12	* Transient expiration times are a maximum time. There is no minimum age. Transients
13	* might disappear one second after you set them, or 24 hours, but they will never be
14	* around after the expiration time.

16	* Pages are cached by the slug that they are published under in WordPress so that they
17	* can be quickly referenced when serving. The entire response when fetching the page
18	* is cached, not just the page HTML content.
