session persistence?

Hi,

this is what I have found in the Aonyx 5.0 documentation:

# Added new features for saving sessions into memory or to disk during
restart enhydra application.see changes and user guide

I looked into the Changes and found the 

SessionManager.MemoryPersistence = true

But somehow it's not enough. And I haven't found a relevant section in
the user guide (actually I haven't found the user guide itself - I was
reading in "Getting Started with Aonyx" - or is there a real user
guide?)
