[Zope] Session Management for keeping Python-Objects

[Stephan Herschel]

Hello,

I have an external method that returns a python-object to zope. Inside
zope i would like to be able to store the object as a session variable
in order to have access to this object inside one session. 
I have tried to do this using FSSession, but it's not able to pickle
objects to a file. Which session management product would you propose
for doing this?

Thanks for any input,
stephan
