title: extjs handle http responses globally
body: <p>I'm a little bit stuck with ajax/http exception handling: I'm trying to handle <code>401</code> exception globally in extjs, and trying to use the following code to do this:  </p>
  
  <pre><code>Ext.Ajax.on('requestexception', function (conn, response, options) {
      if (response.status === 401) {
          log.console = '401 recieved';
      }
  });  
  </code></pre>
  
  <p>It works ok and handles <code>401</code>, BUT only when you explicitly make <code>Ext.Ajax.request()</code>. It doesn't handle ajax stores... So here comes the question: can I handle ALL <code>401 http</code> errors came to my application? Thanks!</p>
