title: HTML5: Why I need to add manifest file to .htaccess?
body: <p>I have seen some articles about HTML5 Manifest, which say that we must add manifest file to .htaccess with following line:</p>
  
  <pre><code>AddType text/cache-manifest .manifest
  </code></pre>
  
  <p>However, there is no any explnation what is the purpose of adding? 
  Where should I place this .htaccess file ? in the same folder where the manifest file is? and finally how can i make sure that it is added to .htaccess successfully?</p>
  
  <p>Even if i do not create any .htaccess file, i only add this to my html file</p>
  
  <pre><code>&lt;html manifest="site.manifest"&gt;  
  </code></pre>
  
  <p>I can see the popup bar in firefox, asking that the website is asking to store data. So isn't it working without this .htaccess? 
  I'll appriciate if anyone can explain. Thanks.</p>
