How it works

Nginx uses the MD5 hash of your fastcgi_cache_key to determine where files are stored in the cache directory. When levels=1:2 is set, Nginx takes the last character of the hash for the first level directory and the next two characters for the second level directory. This hierarchical structure prevents having too many files in a single system directory, which improves performance on many filesystems.
