sessions.backends.base.SessionBase.set_expiry()

set_expiry(value)

Sets the expiration time for the session. You can pass a number of different values:

• If value is an integer, the session will expire after that many seconds of inactivity. For example, calling request.session.set_expiry(300) would make the session expire in 5 minutes.
• If value is a datetime or timedelta object, the session will expire at that specific date/time. Note that datetime and timedelta values are only serializable if you are using the PickleSerializer.
• If value is 0, the user’s session cookie will expire when the user’s Web browser is closed.
• If value is None, the session reverts to using the global session expiry policy.

Reading a session is not considered activity for expiration purposes. Session expiration is computed from the last time the session was modified.
