Thanks, this actually is exactly what I was looking for. I wanted to
store session data in the ram but I thought that would be impossible to
share across a load balanced cluster. Thanks.

Subject: RE: Persistence is a silly marketing gimick
you should be using a session service and not local serialised file
based session storage mechanism. an excellent example is msession
(http://www.mohawksoft.com/phoenix/msession.html) which i use on
relatively high volume sites to solve this very issue. using this
mechanism persistance is only really needed for the HTTPS based
virtual services.
