title: Spring Security doesn't kill session when browser closes
body: <p>I am using Spring Security 3.1 and am using </p>
  
  <pre><code> &lt;concurrency-control max-sessions="1" error-if-maximum-exceeded="true" /&gt;
  </code></pre>
  
  <ul>
  <li>I open a browser and log in (Ex. IE9)</li>
  <li>I close that browser</li>
  <li>I open a different browser (Ex. Firefox)</li>
  <li>I cannot log in because I am still logged in on the other browser</li>
  </ul>
  
  <p>Is there a way to force the session to close when the browser closes? I need to keep the max-sessions to 1 for concurrency control.</p>
  
  <p>Thanks!</p>
