NGINX as proxy before apache, and localy store php generated images

[Jaroslav]

Thank you very much Igor for a fast response!

So far I see the performance increase. I see the logs being created. And no
longer see so lot access logs to apache images.

my config is:
            location /bin/ {
                expires 7d;
                add_header X-Cache "Backend2-cache";
                proxy_pass http://site.com;

                proxy_cache my-cache;
                proxy_cache_valid  200 302  360m;
                proxy_cache_valid  404      1m;
            }

One more question is left in my mind, I see the expire headers are set, but
the HTTP response status is always 200.
is there somewhere a way to make it respond with status 304 (not modified)
?

Thank you
