[ZODB-Dev] ZEO2 tracks session with TemporaryFolder...need confirmation.

[zhimin at iss.nus.edu.sg]

Hello list,

I have a small ZEO cluster (1 ZEO server and 2 ZEO clients) served by a
round-robin load balancer. Using the default setup , I can access Plone
site (residing in ZEO server)  without session conflict. I didn't use any
persistent storage (Berkeley storage, External Mount, DBTab, etc.) to store
session. I just use the TemporaryFolder in the default setup. Also the z2
log shows that the ZEO clients do take turn to serve webpages.

Here's how I test:
    1) Login.
    2) Navigate the site few times. I remain logged in when I navigate the
site, indicating that both ZEO clients are aware of my session state. Am I
correct to say this?
    3) click "my preferences".
    4) copy the URL:
http://myhost.com/myplonesite/portal_form/personalize_form
    5) logout
    6) paste and goto
http://myhost.com/myplonesite/portal_form/personalize_form
    7) Plone notifies me that I am not logged in.

Can anyone tell me if ZEO2 already supports session tracking?
Is the above test valid in testing session tracking? Any idea to test
whether the setup has a correct session tracking setup?
Thanks a lot!
