Robots and favicon declarations

Hello,

I have setup NGINX as a Reverse Proxy on Apache by following the default installation of cPanel. At the generated configuration file "/etc/nginx/conf.d/users/myuser.conf", I see the below lines about the favicon.ico and robots.txt files. What do these declarations exactly mean? Are these files served directly by NGINX instead of being proxied via Apache?

server {
...
    location = /favicon.ico {
        allow all;
        log_not_found off;
        access_log off;
        include conf.d/includes-optional/cpanel-proxy.conf;
        proxy_pass $CPANEL_APACHE_PROXY_PASS;
    }

    location = /robots.txt {
        allow all;
        log_not_found off;
        access_log off;
        include conf.d/includes-optional/cpanel-proxy.conf;
        proxy_pass $CPANEL_APACHE_PROXY_PASS;
    }

    location / {
        proxy_cache $CPANEL_PROXY_CACHE;
        proxy_no_cache $CPANEL_SKIP_PROXY_CACHING;
        proxy_cache_bypass $CPANEL_SKIP_PROXY_CACHING;

        proxy_cache_valid 200 10d;
        proxy_cache_valid 301 10d;
        proxy_cache_valid 302 10d;
        proxy_cache_valid 404 1m;
        proxy_cache_use_stale error timeout http_429 http_500 http_502 http_503 http_504;
        proxy_cache_background_update on;
        proxy_cache_revalidate on;
        proxy_cache_min_uses 1;
        proxy_cache_lock off;

        include conf.d/includes-optional/cpanel-proxy.conf;
        proxy_pass $CPANEL_APACHE_PROXY_PASS;
    }
}

Hey there! Details about the conditions can be found in the Nginx docs, such as the log_not_found entry here:

http://nginx.org/en/docs/http/ngx_http_core_module.html#log_not_found

The bottom section with the proxy_cache_* settings just tells Nginx how long and what to cache. None of these rules have the file handled directly by Apache except the three lines with SKIP.
