title: Set cache expiration?
body: <p>I tested my site with Chrome and got the following recommendation:</p>
  
  <pre><code>The following resources are missing a cache expiration. Resources that do not specify an expiration may not be cached by browsers:
  style.css
  jquery.marquee.js
  jquery.marquee.css
  logo.png
  </code></pre>
  
  <p>How do I set the cache expiration for these files?</p>
