title: Bad values in meta tags
body: <p>I've got a problem when I pass the html5 validator to my site from w3c validator. The errors are next:</p>
  
  <pre><code>Bad value Content-Script-Type for attribute http-equiv on element meta
  &lt;meta http-equiv="Content-Script-Type" content="text/javascript" &gt;
  
  Bad value expires for attribute http-equiv on element meta
  &lt;meta http-equiv="expires" content="Wed, 26 Feb 1997 08:21:57 GMT" &gt;
  
  Bad value pragma for attribute http-equiv on element meta
  &lt;meta http-equiv="pragma" content="no-cache" &gt;
  
  Bad value Cache-Control for attribute http-equiv on element meta.
  &lt;meta http-equiv="Cache-Control" content="no-cache" &gt;
  </code></pre>
  
  <p>What are the correct values to meta tags to pass html5 validator?</p>
