public class scanpage

extends java.lang.Object

The scanpage is a container class. It holds all information that is needed to identify a user, including servlet objects and MMBase session information. It was introduced to make servscan threadsafe but will probably in the future hold all request related information, because we want to extend the model of offline page generation.
