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.
-
When you inherit from the SessionFileContextMixin class you
must call this constructor.
-
Returns the session id.
-
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.
-
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.
-
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.
