title: get the url until the context path
body: <p>I use Icefaces and JSF and I have this problem:
  I have the following url:
  <code>http://myMappedServer/myApp/followingThings</code></p>
  
  <p>I would like to get in my xHtml page the value <code>http://myMappedServer/myApp</code>
  How can I achieve this without using the managed bean?</p>
