title: Help catching session timeout in spring
body: <p>I have a simple Spring 3 MVC application.  I am using a sessionAttribute and everything works fine except when I let the page sit for 30 minutes or longer.  I then get a</p>
  
  <p>org.springframework.web.HttpSessionRequiredException </p>
  
  <p>telling me my object is not found in session.  </p>
  
  <p>I am thinking I need to somehow redirect back to the same page when a session timeout occurs.  I am not sure how to do this correctly with spring.</p>
  
  <p>There is no login required and I am already checking if the object is null.</p>
  
  <p>Any suggestions would be appreciated.</p>
  
  <p>Thanks</p>
