I see subscene using Cloudflare but haven't really taken advantage of it, it can be seen from the header
cache-control: private which means the page will not be stored in the cloudflare cache.
Cloudflare has a very powerful static cache, based on my experience the cloudflare 'cache' can
easily handle 50,000 online users without slowing down the website or causing downtime.
.zip files Use
cache-control: public for users who are not logged in and set expiration in days
- Clear cache in Cloudflare manually if there is a page update
