Horde_Session_Null extends Horde_Session
in package
implements Horde_Shutdown_Task

The null driver provides a set of methods for handling the administration and contents of the Horde session variable when the PHP session is not desired. Needed so things like application authentication can work within a single HTTP request when we don't need the overhead of a full PHP session.
