Hi all,

When I attempt caching these pages as shown below

```
    error_page 404 /404.html;

    location = /404.html {

                root /var/www/prod /templates/;

                internal;

                add_header Cache-Control public;

                add_header X-Cache-Status $upstream_cache_status;

                proxy_cache generalcache;

                proxy_cache_key backend$request_uri;

                proxy_cache_use_stale updating;

    }

```

I don’t see the X-Cache-Status header in the html response. Does that  
mean  
the page does not get cached?

The “proxy\_cache” directive works if you are using proxy\_pass. It  
doesn’t work if you are serving static files as in the config  
above. This is expected behaviour.
