We are using ZEO, a load balancer and nevertheless have sessions in RAM.

True, it is less safe than with persistent sessions -- but it
is also more efficient.

We do this by ensuring that independent of the load balancer's choice
a request for a given session goes to that Zope instance that has this
session.

Refresh only works in debug-mode. You want to tell us that you are
running a production site in debug-mode?


Since when does refresh only work in debug mode? Admittedly we are still
on  Zope 2.7.x, but it works in non-debug mode for me.



Possibly I haven't used Refresh since Zope 2.7 :-) I considered it always 
to be a hack and it raised more problems than it solved.
