title: Content-Encoding: gzip doesn't work for text/html Content-Type
body: <p>I use the config below in my .htaccess. However, whilst other Content-Type get gzipped, the text/html Content-Type doesn't. Anyone knows why?</p>
  
  <pre><code>&lt;IfModule mod_deflate.c&gt;
      AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css text/javascript application/javascript
      BrowserMatch ^Mozilla/4 gzip-only-text/html
      BrowserMatch ^Mozilla/4\.0[678] no-gzip
      BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
      SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip dont-vary
      Header append Vary User-Agent env=!dont-vary
  &lt;/IfModule&gt;
  </code></pre>
