We are looking for ways to generate a new session ID after an user has been authenticated. This is our scenario: - The webapplication contains public and private content - public content is available by http, private/restricted content is only available by https - If the user is logging in, communication is done only by https We now want to generate a new session ID for the user session once he has authenticated in order to prevent session fixation / session hijacking (e.g. if chuck sniffes the http - communication / user doesn't use cookies and publishes a link with ;jsessionid-parameter). The solutions found so far suggested all a HttpServletRequest.getSession(true) after an invalidation: if (session.isNew()) { session.invalidate(); // Invalidate old Session session= request.getSession(true); // Create new Session ID } However running this code on JBoss does not show the expected beheaviour, no new session id is created. System.out.println(session.getID()); // Prints "Foo" session.invalidate(); // Invalidate old Session session= request.getSession(true); // Should create new SessionID System.out.println(session.getID()); // Prints "Foo" again. Any hints how we can work around this issue or what we are doing wrong here are greatly appreciated.
