Actually we can distribute portal session in 2.0 but not *portlet* session.
Maybe that's what you wanted to express in your post.
Production ready for 2.2 should be by the ned of this year.
yes sorry... I meant portlet session. I want to keep for example the search result in a portlet when one of the machines go down.
Thanks for the reply.
so what you are looking for is in 2.2
