[Zope] ZEO and session variables.

[Dennis Allison]

I am just setting up a multi-headed distributed system with several Zope
heads all communications with a ZEO backend.  The zopes can be on the same
machine or on different machines connected through a high speed backbone.  
In our system, all zopes are frontended with pound.

      zope2----- ZEO-----zope3
                  |
                zope4

We make heavy use of session variables.  Normally, with a single Zope
session variables are stored in a temporary folder, but, as such, they are
are not shared between the zope heads.   In the multiheaded system, the
session variables need to be shared and therefore must be managed by 
ZEO.   What is the recommended best practice for this?
