title: AJAX calls not hitting server after using back button
body: <p>I'm, making a simple AJAX call on page load...</p>
  
  <pre><code>$(document).ready(function() {
      $.get('', {'format': 'json'}, function(items) {
          console.log('hello');
      }
  }
  </code></pre>
  
  <p>If I hit a link on the page, then use the back button, the code above runs (it outputs 'hello' to the console), but the request never hits the server, it just uses the response it had originally as if it was cached.</p>
  
  <p>Is it possible to force it to hit the server?</p>
