title: Session timeout kills "Remember Me" cookie in aspnet database
body: <p>I'm trying to understand if this makes sense:</p>
  
  <pre><code>1. User logs in, checks "remember me" checkbox.
  2. User logs out.
  3. User comes back and is automatically logged in.
  </code></pre>
  
  <p>Basically, that's exactly what you'd expect to happen.  This means it's working.  Here's where it gets a little weird:</p>
  
  <pre><code>1. User logs in, checks "remember me" checkbox. (Or logs in using remember me.)
  2. User is inactive for over 20 minutes, so the session times out.
  3. User clicks a link and is sent to the sign in page.  
  4. User closes browser, then opens again.  They are taken to the sign in page.
  </code></pre>
  
  <p>It would seem that "Remember Me" is turned off for this user when their session expires due to inactivity.  I've tried to find something about this in the documentation, but to no avail.  If this is expected behavior then that's cool, but I'd like to confirm.</p>
  
  <p>We're using the Sitecore.Security.Authentication manager to set the cookie in the first place.</p>
