##
7.7.5 SessionFileContextMixin

This class works in concert with the `SessionFileAppMixin` application mixin class to store session data in the local file-system. All management of session data storage is performed by the application class.

Inherits from the `SessionBase` class so you must call the constructor if you subclass this class.

`__init__`( | )

  When you inherit from the `SessionFileContextMixin` class you must call this constructor.

`sesid`( | )

  Returns the session id.

`load_session`( | )

  This is usually called from the `Application` class `load_session()` method. Retrieves the session id and then either retrieves an existing session or creates a new session via the application object.

  If an existing session is retrieved it is passed to the `decode_session()` method (inherited from the superclass). If an exception is raised during `decode_session()` then the session will be deleted from the server and a new session will be created via the application object `new_session()` method.

`save_session`( | )

  This is called from the `Application` class `save_session()` method at the end of the request processing sequence. If the session save flag has been cleared via the `set_save_session()` method then the session is not saved.

  Before saving a session the method calls the superclass `encode_session()` then calls the `put_session()` application method to save the session.

`remove_session`( | )

  This is called from the `Application` class `remove_session()` method. The method calls the superclass `remove_session()` then calls the `del_session()` application method to remove the session at the server.
