Class StandardSession

java/org/apache/catalina/session/StandardSession.java:68–1458

Standard implementation of the Session interface. This object is serializable, so that it can be stored in persistent storage or transferred to a different JVM for distributable session support. IMPLEMENTATION NOTE : If you add fields to this class, you must make sure that you carry

 * read/writeObject methods so that this class is properly serialized.
