How does Cache Preloader work?

The?Preload Cache?feature?emulates a visit to your site’s pages to generate?cache

The preload will run when you first press the preload “Run” button under Cache >> Preload >> Preload now.

You can then set up a schedule. If your cache lifespan is 24 hours and you select the option to run at the same time as your cache lifespan and the time is now 17.34 then the preload should run every day at 17.34

Similarly if you set the preload to every 24 hours, the preload will occur at 17:34 every day.

There are full preloads, these happen when when you click the?Clear and preload cache?button. The purge cache is when you goto purge cache >> purge cache for all pages in the top toolbar (if you have this enabled) or if you goto cache >> page cache>> purge the cache

Partial cache preloading takes effect when WP Rocket automatically clears the cache for the following URLs:

• Published or updated URLs, such as posts/pages/custom post types
• Pages purged when the?cache lifetime expires.

The time taken will vary depending on the number of pages and your server settings.
