title: window.location in IE base href
body: <p>I'm having an issue with Internet Explorer and the window.location.</p>
  
  <p>I'm using Backbone.js for my backend project.</p>
  
  <p>The base URL is '<a href="http://www.domain.com/admin/" rel="noreferrer">http://www.domain.com/admin/</a>'</p>
  
  <p>And my js function looks like :</p>
  
  <pre><code>openFolder : function(e) {
          var folder_id = '4';
          window.location = "controller/folder/" + folder_id;
      },
  </code></pre>
  
  <p>So when I'm on the page 'www.domain.com/admin/controller' and I click on a button to open folder, it work well on all browser except for Internet Explorer that redirect me to
  '<a href="http://www.domain.com/admin/controller/controller/folder/4" rel="noreferrer">http://www.domain.com/admin/controller/controller/folder/4</a>'</p>
  
  <p>Can you help me with this issue ?</p>
  
  <p>Thank you
  Ilan</p>
