title: Get previous router/url in backbone application
body: <p>I have a backbone application and i would require to know the router from which the current route is accessed. Is it possible?</p>
  
  <p>For eg :-</p>
  
  <p>I reach <code>#/current</code> from <code>#/test1</code> and also in another instance, from <code>#/test1</code>.</p>
  
  <p>So can i know through some way to detect the previous router hit?</p>
  
  <p>Ive used :</p>
  
  <pre><code>Backbone.history.fragment
  </code></pre>
  
  <p>and this only gives me the current route accessed and not from which route. </p>
