   A backend server sends 'Cache-Control: no-cache' headers on responses, which instructs NGINX to revalidate the content with the origin before serving a cached copy. The team wants NGINX to honor this behavior using conditional requests (If-Modified-Since/If-None-Match). Which directive enables this?

   • Aproxy_cache_revalidate on;
   • Bproxy_cache_valid 200 1h;
   • Cproxy_cache_lock on;
   • Dproxy_cache_bypass $http_cache_control;
