I noticed in the metrics sections of the app, there is an HTTP Cache Ratio. I was curious what cache this was referring to and how to use it correctly. I have an in-memory cache and Redis cache. I was curious if Fly had a cache itself? Is there a header that needs set for this to report correctly? …

[[statics]] has nothing to do with this. Well… we do add add proper headers for cache hits. If your server responds with the correct headers, we’ll log these metrics for you. The header to add to your responses is fly-cache-status: HIT|MISS|<whatever>.

Aloha,

It must be to do with the [[statics]].
