nginx 0.7.64 ignoring Cache-Control headers

Hey guys, I apologise if this is covered in another topic, I have searched many pages on the forum and not come across this issue.

I'm using nginx v. 0.7.64 with the following: --with-debug --with-http_stub_status_module --with-http_flv_module --with-http_ssl_module --with-http_dav_module --with-http_gzip_static_module --with-mail --with-mail_ssl_module --with-ipv6

I've configured a host to reverse proxy to Apache with proxy_store enabled:

        location / {
                proxy_pass http://localhost:8080;
                proxy_redirect off;

                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

                client_max_body_size 10m;
                client_body_buffer_size 128k;

                proxy_connect_timeout 90;
                proxy_send_timeout 90;
                proxy_read_timeout 90;

                proxy_buffer_size 4k;
                proxy_buffers 4 32k;
                proxy_busy_buffers_size 64k;
                proxy_temp_file_write_size 64k;

                if ($request_uri ~ /$) {
                        set $store_extra index.html;

                proxy_store /tmp/nginx/$http_host/${uri}${store_extra};
                proxy_store_access user:rw  group:rw  all:r;

And placed several test PHP files in to the host directory with different Cache-Control headers

header("Cache-Control: private,max-age=0");
echo "test";

header("Cache-Control: public,max-age=3600");
echo "test";

When I access both files with Firefox and inspect their headers using Live HTTP Headers I can see that the correct Cache-Control headers are there, yet nginx is ignoring them and caching both files.

Am I missing a module or a patch? I was advised in another post that this was one of the ways to control which files nginx actually cached and this seemed like the best approach to it.
