The only methods you have to implement are :meth:`open_session` and :meth:`save_session`, the others have useful defaults which you don't need to change. The session object returned by the :meth:`open_session` method has to provide a dictionary like interface plus the properties and methods from the :class:`SessionMixin`. We recommend just subclassing a dict and adding that mixin:: class Session(dict, SessionMixin): pass If :meth:`open_session` returns ``None`` Flask will call into :meth:`make_null_session` to create a session that acts as replacement if the session support cannot work because some requirement is not fulfilled. The default :class:`NullSession` class that is created will complain that the secret key was not set. To replace the session interface on an application all you have to do is to assign :attr:`flask.Flask.session_interface`:: app = Flask(__name__) app.session_interface = MySessionInterface() Multiple requests with the same session may be sent and handled concurrently. When implementing a new session interface, consider whether reads or writes to the backing store must be synchronized. There is no guarantee on the order in which the session for each request is opened or saved, it will occur in the order that requests begin and end processing. .. versionadded:: 0.8 Fappr rr5cCs|S)aCreates a null session which acts as a replacement object if the real session support could not be loaded due to a configuration error. This mainly aids the user experience because the job of the null session is to still support lookup without complaining but modifications are answered with a helpful error message of what failed.
