Hi,

your system has already a file cache memory. It does the trick.
If you want to use nginx cache capabilities, you can make nginx
reverse proxies all requests to apache (even static ones) and set up a
cache (proxy_cache* directives). But ningx will put cached files on
disk et read them on demand. It will benefits of system cache as well.

I asked myself the same question weeks ago but in my case static files
were not on a local disk but on a NFS shared disk. So I let apache to
serve statiques pages as well and cache them localy.

Hope it helps
