title: CakePHP auth session vs. cookie not updating
body: <p>I have a ACL+auth driven app. Everything works fine but I discovered that user is logged out after a random period of time. After doing some research I discovered that the cookie set once doesn't change it's expiration date on page refresh. So it goes like this: </p>
  
  <p>I set up manually expiration time to 1 minute (Security.level low (with some changes in cake/libs) and timeout 60)</p>
  
  <p>19:00:00 - user loads the page - cookie is set up</p>
  
  <p>19:00:05 - user logs in (cookie doesn't change the expiration date)</p>
  
  <p>19:00:30 - page refresh (cookie doesn't change the expiration date)</p>
  
  <p>19:00:55 - page refresh (cookie doesn't change the expiration date)</p>
  
  <p>19:01:05 - page refresh - user is logged out... (cookie expired after 1 minute)</p>
  
  <p>So the problem is the user gets logged out after 60 seconds from setting a cookie in instead of 60 seconds of inactivity. Does CakePHP deal with cookie files automatically? Or do I have to take care about it myself? 
  All I did is set up a cookie name in config/core.php and setup auth. I don't have any cookie handling function, but the cookie is created itself - correctly, just isn't updated</p>
