title: How to override base url of joomla
body: <p>I want to override the root Url of a Joomla site. JURI::base(true) is the 
  problem because it returns / . How can I change this?</p>
  
  <p><a href="http://docs.joomla.org/JURI/root" rel="nofollow">http://docs.joomla.org/JURI/root</a> lets me override the root, but components like
  the breadcrumb and logout use something else, probably JURI::base().</p>
  
  <p>thanks</p>
