- * Session management class
- * http://www.developpez.net/forums/d51943/php/langage/sessions/
- * http://sebsauvage.net/wiki/doku.php?id=php:session
- * http://sebsauvage.net/wiki/doku.php?id=php:shaarli
- *
- * Features:
- * - Everything is stored on server-side (we do not trust client-side data,
- *   such as cookie expiration)
- * - IP addresses + user agent are checked on each access to prevent session
- *   cookie hijacking (such as Firesheep)
- * - Session expires on user inactivity (Session expiration date is
- *   automatically updated everytime the user accesses a page.)
- * - A unique secret key is generated on server-side for this session
- *   (and never sent over the wire) which can be used
- *   to sign forms (HMAC) (See $_SESSION['uid'] )
- * - Token management to prevent XSRF attacks.
- *
- * TODO:
- * - log login fail
- * - prevent brute force (ban IP)
- *
- * HOWTOUSE:
- * - Just call Session::init(); to initialize session and
- *   check if connected with Session::isLogged()
