Re: [Zope-dev] How would I keep _v_* attributes from getting thrown away?

I am using ZODB along with CORBA to expose peristent objects. Some of my objects have per-connection/session state. ... My initial idea is to have a _v_position attribute ... Using "_v_" attributes for session state is a very bad idea. They are thread(!) local and not session local. This means, if a following request of your user (in the same session) happens to get assigned a different thread, it will read and update a different position. Chaos is garanteed (though you will see it only, if your site is loaded).

Use a session product (-> zope.org) for session data. Dieter
