HTML files are minified dynamically by removing comments and unnecessary empty lines only. It does not require files to be cached. CSS and JS minification operates on cached CSS and JS files only. Once Cloudflare returns a cache HIT for the file it will be returned to browsers in minified form. This allows us to deliver a more complete minification result. If you need to enable or disable minification for CSS & JS you will now need to purge your Cloudflare cache to see the effect of any minification change.
