title: Expire ASPXAUTH Cookie when browser closes
body: <p>I'm creating an ASPXAUTH cookie by using the following code</p>
  
  <pre><code>var authTicket = new FormsAuthenticationTicket(2, model.Name, DateTime.Now, DateTime.Now.AddMinutes(ConfigSettings.SessionTimeout),
                      false, result.UniqueId.ToString());
  
                  var authCookie = new HttpCookie(FormsAuthentication.FormsCookieName,
                      FormsAuthentication.Encrypt(authTicket))
                  {
                      HttpOnly = true,
                      Expires = authTicket.Expiration                    
                  };
  
                  Response.AppendCookie(authCookie);
  </code></pre>
  
  <p>When the user closes the browser (both IE and Chrome) and logs in again the session is still active, the APSXAUTH cookie is not expired.  I've set it to be non persistent.  I'm also certain all browser instances have been closed.</p>
  
  <p>What am I missing?</p>
