[Zope] ZEO, Persistent Sessions

[Travis Miller]

hi,

my zeo setup is running like a top :-) ...until!

i would like my zeo clients to share the same session storage.

out of the box, zope has a temporary storage database (/temp_folder) 
for the session data (/temp_folder/session_data). the session data 
manager (/session_data_manager) is then configured to pull from the 
session data (/temp_folder/session_data).

my first inclination was to create another session data object 
(/session_folder/session_data) in the main database and to configure 
the session data manager to pull from it. (i've also tried using a 
separate zeo filestorage and mounting it. as expected, i saw the same 
results through out.)

however, when i do this, it seems as though only one zeo client is 
allowed to use the session. a simple python script that prints 
request.SESSION succeeds on one client, but fails with a key error on 
the other.


Traceback (innermost last):

i have:
   python 2.3.4
   Zope 2.7.1
..compiled from source


this was all i could really find on zeo clients sharing sessions. it 
seems to support what i have attempted:
   http://www.zopelabs.com/cookbook/1061234337


what might i be missing?
if sharing the session is a bad idea. where else could i store session 
like information for a script based application?


thanks for any help


thanks,
travis
