Sessions in MoinMoin are implemented using a special session handler that can be configured in cfg.session_handler. By default, an instance of the class MoinMoin.session.DefaultSessionHandler is used for managing sessions. Code using the session framework currently includes: the superuser "change user" functionality, see HelpOnSuperUser the visited pages trail

cookie_domain None Domain used in the session cookie. cookie_path None Path used in the session cookie. cookie_lifetime 12 =0: forever, ignore user 'remember_me' setting; >0: n hours, or forever if user checked 'remember_me'; <0 -n hours, ignore user 'remember_me' setting anonymous_session_lifetime undefined Set this to a non-zero value to enable anonymous sessions (can be fractional) [hours]. (!) If you run a wiki farm and you want to share the session cookie between farm wikis, you want to change cookie_domain and/or cookie_path. (!) If you want anonymous users to get session features (e.g. a trail), set anonymous_session_lifetime.

Should you wish to store session data somewhere other than the filesystem cache Moin uses, you can use the DefaultSessionHandler along with a different class descending from DefaultSessionData. See MoinMoin/session.py for more details. It is also possible but not recommended to use a different session handler altogether.

As an extension programmer, in order to use session variables, you can use request.session like a dict, values stored there are automatically saved and restored if a session is available. Some more advanced usage is possible, see MoinMoin.session.SessionData in the file MoinMoin/session.py. Here's an example macro using the session code:
