Hi Maxim,



Thank you for this. Opened my eyes.



Not to sounds demanding, but do you have any examples (code) of proxy_store
bring used as a CDN. What’s most important to me in the initial cache
warming. I should be able to start a new machine with 30 GB of cache vs. a
cold start.



Thanks once again.



- Quintin
