title: HTTP Header Stylesheets
body: <p>According to this: <a href="http://www.w3.org/TR/html4/present/styles.html#h-14.6" rel="nofollow">http://www.w3.org/TR/html4/present/styles.html#h-14.6</a>
  I can link stylesheets directly in the http header. 
  In php it would look like this:</p>
  
  <pre><code>header('Link: &lt;http://www.acme.com/corporate.css&gt;; REL=stylesheet');
  </code></pre>
  
  <p>are there any drawbacks in doing this?</p>
