+ * 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()
