# A modern default for caching is to actually do no caching at all, and use CDNs to bring your content close to your users.
# Every time a user loads your site, they'll go to the network to see whether it's up-to-date.
# This request will have low latency, as it'll be provided by a CDN geographically close to each end user.
#  Cache-Control: no-cache for resources that should be revalidated with the server before every use.
#  Cache-Control: no-store for resources that should never be cached.
#  Cache-Control: max-age=31536000 for versioned resources.
