"On" are invalid parameters.

Why do you want to cache image from localhost ?
You should handle them as static files.

"break" is useless here. It's just waste of CPU cycles.


--------

So I should just really just use cache like this:
      location ~ \.php$ {

                         fastcgi_index index.php;
                         fastcgi_pass 127.0.0.1:9000;
                        fastcgi_cache cachephp;
                         fastcgi_cache_key 127.0.0.1:9000$request_uri;
                         fastcgi_cache_valid 200  1h;
                         include fastcgi_params;
	}

And images like this:       
	location ~* \.(jpg|jpeg|gif|css|png|js|ico|tif)$ {
                         access_log off;
                         expires 30d;
	}

That would be best for performance?

Also, I noticed when I use the fastcgi_cache above that it caches logged in
pages and users see the wrong user profile... should I change the
fastcgi_cache_key to fix that?
