Calling session.save()

Hi,

Is it costly to call session.save() if the session has only been used for
reading?

Frank,

I hadn't spotted that method. Thanks

I don't really know, but if so, you could consider using boolean  
Session.hasPendingChanges() to see if there is any change to save  
before saving. (But be careful of concurrent access then.)
