And that is exactly what reddit does:

«
cache-control:max-age=0, must-revalidate
cf-cache-status:HIT
cf-ray:23558623ce9b231e-FRA
»

As you can see my request for /r/programming at reddit.com found 
a hit in their CDN cache Cloudflare...

CDNs may allow explicit preloading and removal of outdated 
resources from caches (contrary to HTTP).
