A session is started when HttpRequest.getSession() is called. The session will then be added to the session manager. The session manager then controls timeouts. The session id is create by using the a crypto-random sequence of 16 bytes. These are extracted by using /dev/urandom on posix and CryptGenRandom on windows.
