title: Symfony 1.4 cookie issue
body: <p>I am trying to find where Symfony is setting a cookie. When I visit my site (I'm using the sfDoctrineGuard plugin) I get the login page, which is the expected behaviour. When viewing the cookies that have been created, there is a 'symfony' cookie. I can't find where Symfony is setting this cookie... I need to change the expiry time.</p>
  
  <p>The only places that I see setCookie being used is for the Remember Me key but this is a separate cookie altogether.</p>
  
  <p>The other problem is that for some reason, the expiry time for the 'symfony' cookie is showing as "Session" in Safari, and not a date/time.</p>
  
  <p>I'm pretty sure this has nothing to do with sfDoctrineGuard, and that Symfony always creates a cookie when a user visits the site, just need to find the code that is setting this cookie.</p>
  
  <p>Any ideas?</p>
