... Jean, try to avoid needless writes to the session object. For example throw some conditional code in your access rule of the form:

if session.get(key) != value: session.set(key,value)

That should help reduce the number of "ConflictError"s.

Note, however, that reading the session writes it (in order to update the expiration deadline).

I figured that there is some kind of filtering for updating the expiration deadline. The filtering reduces excessive writes at the expense of the accuracy of the deadline. Michael
