http {
    [...]

    proxy_cache_path /opt/nginx/cache levels=1:2 keys_zone=one:10m;

    [...]

        server {
        listen       127.0.0.1:8000;
        server_name  localhost;
        access_log  /var/log/nginx/one.access.log  main;
        location / {
            proxy_pass         http://192.168.10.10:80/;
            proxy_redirect     off;

            proxy_cache        one;
            proxy_cache_valid  200 1h;
            [...]
        }
    }

Declaring cache ( proxy_cache_path ) and caching ( proxy_cache ) should
be enough.

Proxy_cache_valid in above example is used to enforce caching for
objects that have no declaration on caching.
