title: PageSpeed Insights not seeing the Gzip compression
body: <p>I'm trying to speed up my website. Google insights (<a href="https://developers.google.com/speed/pagespeed/insights" rel="nofollow noreferrer">https://developers.google.com/speed/pagespeed/insights</a>) tells me that a critical problem is to enable GZip compression.</p>
  
  <p>The address of the site is <a href="http://user2.net" rel="nofollow noreferrer">http://user2.net</a>
  It's based on codeigniter framework.</p>
  
  <p>I have enabled gzip compression with folowing changes to my .htaccess file:</p>
  
  <pre><code>AddOutputFilterByType DEFLATE text/plain
  AddOutputFilterByType DEFLATE text/html
  AddOutputFilterByType DEFLATE text/xml
  AddOutputFilterByType DEFLATE text/css
  AddOutputFilterByType DEFLATE application/xml
  AddOutputFilterByType DEFLATE application/xhtml+xml
  AddOutputFilterByType DEFLATE application/rss+xml
  AddOutputFilterByType DEFLATE application/javascript
  AddOutputFilterByType DEFLATE application/x-javascript
  
  
  &lt;files *.html&gt;
  SetOutputFilter DEFLATE
  &lt;/files&gt;
  </code></pre>
  
  <p>I have tested the site with this tool:
  <a href="http://www.gidnetwork.com/tools/gzip-test.php" rel="nofollow noreferrer">http://www.gidnetwork.com/tools/gzip-test.php</a>
  It says that gzip is enabled.</p>
  
  <p>What am I missing?</p>
