We noticed that one of our user's session info in django_session has it's
expire date moved into the future periodically. We are not calling
set_expiry() on the session. My understanding was that the expire date was
a constant for a given session key -- it is set when the session is
created and never changes unless set_expiry() is called.
While reading through the Django Sessions docs, though, I noticed this
bit:
{{{
To change this default behavior, set the SESSION_SAVE_EVERY_REQUEST
setting to True. If SESSION_SAVE_EVERY_REQUEST is True, Django will save
the session to the database on every single request.
Note that the session cookie is only sent when a session has been created
or modified. If SESSION_SAVE_EVERY_REQUEST is True, the session cookie
will be sent on every request.
Similarly, the expires part of a session cookie is updated each time the
session cookie is sent.
}}}
Does this mean that the cookie is sent whenever the session data changes
and that this triggers the expiration date to move forward? If so, why is
that? It seems that's the wrong behavior since I would think the
expiration of someone's remembered login etc would have nothing to do with
when the session data was last updated.
