When B is serialized, so is A, and serialization makes sure the instances to your object are kept shared....

how can this be?  Aren't different pages written to different streams
and thereby incapable of sharing objects?

Yes, I believe you are correct.

But when A is serialized alone (and if A does not have a reference to B), then when A is deserialized you'll have a copy of the instance you gave to B and the reference is no longer shared.

 So the best thing is that you shouldnt depend on shared variablen.

Ok so there are a lot of gotchas :)

Yep!

ok, I'll go ahead with storing the object in the session directly (as
meta-data) and use models in the pages to access this object.

May I ask what your use case is?
