title: CAS logout and cookies elimination
body: <p>I just made a HelloWorld servlet and implemented CAS on it.
  I'm being able to log in without problem and CAS is setting 3 cookies in my browser, the CASGT, and 2 JSESSIONID 1 for /cas and another for /helloWorld</p>
  
  <p>The problem is that then I access <a href="https://blah:8443/cas/logout">https://blah:8443/cas/logout</a>, I see the logged out succesfuly screen but the cookies still are in my browser, so I'm not being loged out, I can get in again in /helloWorld without the login screen showing up.</p>
  
  <p>Do you know what should I do for CAS to delete the cookies it created when I log out?</p>
  
  <p>Thanks in advance </p>
