title: Allow access to folder only from specific IP Address (or domain) and Port using .htaccess
body: <p>I am trying to secure access to a PHP page in a folder and only allow access to it from a specific IP Address and domain name but only on a specific port. I have seen a number of questions here but not including the PORT access.</p>
  <p>I have added the following in the .htaccess file within the folder.</p>
  <pre><code>order allow,deny
  deny from all
  allow from 111.222.333.44:12345
  </code></pre>
  <p>However, this seems to be invalid.</p>
  <p>What would be the correct way of doing it?</p>
