title: Ban IPs from text file using htaccess
body: <p>I read and understand how to block an ip using htaccess:</p>
  
  <pre><code>order deny,allow
  deny from 111.222.33.44
  deny from 55.66.77.88
  ...
  allow from all
  </code></pre>
  
  <p>But my list of black IPs includes thousands of IPs.
  I save all IPs to a <strong>blacklist.txt</strong> file.</p>
  
  <p>Can I use htaccess to call <strong>blacklist.txt</strong> and block all IPs which are stored in this file? If so, how?</p>
