Hello, I read from the list
"zone_size" is a size of keys_zone, i.e. shared memory zone used to store cache keys (some minimal metadata about cached pages, about 64 bytes on 32-bit platforms).
but what does this practically mean ?
Let say a new request arrive and the request has to be cached. What does NGINX do if the "space" in the shared memory is over ? It delete the oldest file in the cache (and the key too) ?
Is there a rule to size this parameter ?
