Countermeasures
session.invalidate; session=request.getSession(true);
 * Session ID should be regenerated after login, and switching in and out of SSL

Comment: Please note that JBOSS has proven to NOT regenerate a new session id via this method as of December 2007.


 * Disable URL rewriting

Comment: What threat does this mitigate? Answer: Disabling of URL rewriting mitigates Session Hijacking/Session Sniffing via session id's being exposed in a GET parameter of your url's (as well as being stored in your browser history, proxy servers, etc). See Session hijacking attack
