title: Deny access permissions - apache, linux
body: <p>How can I deny access permission to an entire folder except one file?
  For example, my <code>DocumentRoot</code> is <code>"/var/www/html"</code> and there I have a folder called <code>example</code>. In there, there are many files and one of them is <code>index.php</code>. So I want to give access permission only to this file, and deny access permissions to the other files in that folder.</p>
