The plugin is an improved version of the “Cloudflare Page Cache” plugin. The plugin does not cache pages for logged-in users by default. You can disable caching for some URLs and for users with certain cookies (use the constants BYPASS_COOKIES_EXTRA and NON_CACHEABLE_URLS_EXTRA for the settings). 
For the plugin to work, you need to have a Cloudflare account with special settings. To purge the cache by the button, you need to set Cloudflare API settings in the plugin (CF_EMAIL – From https://dash.cloudflare.com/profile, CF_API_KEY – Global API Key from https://dash.cloudflare.com/profile, CF_ACCOUNT_ID, CF_NAMESPACE_ID). 
In the Сloudflare account, you need to create a worker, for details go https://github.com/palessit/cloudflare-cache-page. The plugin can preload cache on Cloudflare.
