title: Set user as online in asp.net membership
body: <p>When a user sets the option (remember me) and closes the browser and then opens the site again he does not appear listed with the on-line members.</p>
  
  <p>How can I set a user to <code>on-line</code> after the user reopens the site again?</p>
  
  <p>I am using this code <code>Membership.GetNumberOfUsersOnline();</code> but it returns 0 on-line</p>
