title: How do I delete a session key in Django after it is used once?
body: <p>I have two views. </p>
  
  <p>view1 passes an error message to view2 through a session key. </p>
  
  <p>How do I delete the key after view2 is rendered? I only need it for once:  redirect from view1 to view2. I dont need that message to show up after refreshing my webpage. I don't think python will continue to execute once it reaches <code>return</code></p>
  
  <p>I was thinking about setting an expiration timestamp but I need to ensure that it exists for at least 10-20 seconds, if the application really does that long to load (we do some server stuff with Django)? So time is not that promising.</p>
  
  <p>Thanks.</p>
