What does Automatic Cache Management in the Cloudflare Plugin do?

The Cloudflare WordPress plugin contains a feature known as Automatic Cache Management. When a user adds/edits/deletes a post, page, attachment or comment - all associated URLs containing that content will be purged from the Cloudflare cache. When you switch a theme or customise a theme within the WordPress admin panel, the cache will automatically be cleared too.

This feature works great when caching HTML on WordPress with the Bypass Cache on Cookie setting.
