Last Updated: February 2, 2022

Latest News: I updated the documentation.

The following information talks about WP Super Cache CDN and Contents settings. These settings are important to manage and set up correctly from the beginning. The CDN feature is only needed if you are going to set up CDN “Content Delivery Network” on your site. Otherwise you don’t need to enable this feature.

The Contents feature allows you to manage all the cache currently served by the plugin. Here is were you delete all the content and regenerate new content for your site.

Note: Depending on the size of your site, these features can help you but make sure you carry out some test before you enable and save these settings.
