I would like to replace a reverse proxy server. I would like to move the proxy cache so it does not have to fetch every file from the origin server again.

Are the file-names inside the cache based on anything besides the proxy_cache_key?

I use these two settings:


proxy_cache_path /nginx-cache/thumbs levels=1:2 inactive=14d keys_zone=thumbs_cache:1000m max_size=600000m;
proxy_cache_key $uri;

Thanks!
