title: embed an external link in django app
body: <p>I added a link in myproject/templates/items/index.html like this</p>
  
  <pre><code>&lt;a href="www.google.com"&gt;Search More&lt;/a&gt;
  </code></pre>
  
  <p>My hope was that when a user clicks it, she would visit google.com. However, the result right now is this link is "myhost/items/www.google.com" instead of "www.google.com".</p>
  
  <p>(I am modifying an existing app, and I have to admit I have not fully read django doc yet) </p>
