What are the configuration steps to enable Cloudflare Cache Reserve for a WordPress installation?

To enable Cache Reserve, you typically navigate to your Cloudflare dashboard, go to the 'Caching' section, and then find 'Cache Reserve.' You'll need to enable the feature, which often involves selecting or creating an R2 bucket (Cloudflare's object storage) where the reserve cache will be stored. While there's no specific WordPress plugin just for Cache Reserve, ensuring your WordPress site's caching headers are correctly configured (e.g., using a plugin like WP Rocket, LiteSpeed Cache, or custom code to set `Cache-Control` headers) is crucial for Cloudflare to know what to cache and for how long.
