/**
* This action creates and terminates a session.
* The action is controlled via parameters. The action parameter defines
* the action (creating or terminating).
* The value "create" creates a new session (if not already available)
* The value "terminate" terminates the session. The termination can be controlled
* with a second parameter "mode": The default value "immediately" terminates
* the session, the value "if-unused" terminates the session only if no
* session context is available anymore. This means the user must not have
* any own session context and must not be authenticated anymore using
* the uthentication framework.
