I don't think the question is whether you can migrate a session from one
worker to another, the question should be do you really want to.
Sessions by their very nature are not transaction managed. So, even if your
server supports session migration you never really know what state your
session is in. For persistency and transaction management you should use a
database. That's what they are designed for.
There are servers, like weblogic, that support session migration. If you
decide to use this feature you will incur a great deal of extra overhead and
your performance will suffer.
