XWiki 1.0 - Session Management

Hi, I would like to know how the session management is being done in xwiki - 1.0. Specifically - how does xwiki check if the user is still logged in before directing to login page (assuming the options are set on the xwiki) In the 0.984 version, the cookie - "username" was being set whenever the user logged in and lasted until the user logged out. I had used that cookie outside of xwiki (in external application) for checking if the user was logged in to xwiki. But it is no longer present in the 1.0 version. Need your inputs/directions/thoughts if I can use analogous mechanism in xwiki1.0.
