title: disable or block streaming, video and audio in squid proxy
body: <p>I'm working in a squid proxy and I need to disable or block streaming, video and audio. I read about mime types who can disable or block videos from youtube, vimeo or other type of things.</p>
  
  <p>I found this:</p>
  
  <pre><code>acl deny_rep_mime_flashvideo rep_mime_type video/x-flv
  http_reply_access deny deny_rep_mime_flashvideo
  </code></pre>
  
  <p>And when I start the Squid.. nothing happened.</p>
  
  <p>Can you help me with this problem?</p>
