[Zope] Session and objects

[Bo M. Maryniuck]

Hello, all.

I would like to handle session events. For example: user closes browser, =
etc.=20
Seems that is not possible, so I desire do it via the Session. But... is =
it possible=20
to add somethin non-string'ish into the SESSION? For example, I would lik=
e add=20
the an DB connecton or DB cursor or any other object.=20
But Zope tells me something like:

Error Type: InvalidObjectReference
Error Value: Attempt to store an object from a foreign database connectio=
n

Traceback (innermost last):

\x00\x00\x00\x00\x00\x00\x00\x0b', ''))
InvalidObjectReference: (see above)

Is here some workaround or advantage?
