Create a Pull Zone
Log in to your bunny.net dashboard, create a new Pull Zone, and set the origin URL to your WordPress site. For more details, see How to create your first Pull Zone.
Install WP Rocket
Purchase and download the WP Rocket plugin from their website. In your WordPress admin, go to Plugins → Add New, upload the ZIP file, and activate the plugin.
Configure the CDN
Click the WP Rocket option in your WordPress admin bar, then go to CDN Settings. Enter the full hostname of your Pull Zone (including 
https://) and save your changes.
WP Rocket forces a no-cache instruction (
max-age=0) on HTML files to ensure
those pages are treated as dynamic. HTML pages will not be cached on the CDN
unless you configure this explicitly via WP Rocket settings or an Edge Rule on
your bunny.net Pull Zone.
