Code description:

proxy_cache_key $uri defines the unique key of the cache, which is used for hash access through the unique key

proxy_cache_path cache file path

levels set the cache file directory level; levels=1:2 means two-level directory

keys_zone sets the cache name and shared memory size

inactive will be deleted if no one is accessed within the specified time. 30m means 30 minutes

max_size is the maximum cache space. If the cache space is full, the resource with the longest cache time will be overwritten by default.

proxy_cache_valid Cache validity time, regardless of whether it is accessed during the inactive time, as long as the cache expires at the proxy_cache_valid time, the data will be re-requested.
