title: How do I keep a user logged into my site for months?
body: <p>I'm using OpenID. How do I make it so that the user stays logged in for a long time even after closing the browser window?</p>
  
  <p>How do I store and get access to the user's <code>User</code> object?</p>
  
  <p>Basically, I guess I just don't really understand how sessions work in Java.</p>
