title: Web root option in Varnish Cache similar to `root` in nginx
body: <p>In nginx we have <code>root</code> option to serve files from a specific directory, eg: <code>root /var/www/data/</code> in nginx conf, if my url is <a href="https://mydom.com/$file_name" rel="nofollow noreferrer">https://mydom.com/$file_name</a>, nginx will look for files present in <code>/var/www/data/$file_name</code> and return the file if present otherwise return 404.</p>
  <p>Now, I want something similar option in Varnish. Is there a way where I can serve files from a specific directory? How can I tell varnish to look for files in a specific directory and return that file?</p>
