title: Devise Remember Me and Sessions
body: <p>I'm confused with the devise gem config settings:</p>
  
  <pre><code>  # The time the user will be remembered without asking for credentials again.
    config.remember_for = 2.weeks
  
    # The time you want to timeout the user session without activity. After this
    # time the user will be asked for credentials again.
    config.timeout_in = 10.minutes
  </code></pre>
  
  <p>I want to have a user select the "Remember Me" checkbox (i.e., keep me logged in), but the default session timeout is 10 minutes.   After 10 minutes it asks me to log in again even though I have clicked "Remember me".  If this is true then the remember_for is really meaningless.   Obviously I'm missing something here.</p>
