Torsten,
did you have a look at Servlet API 2.3 session attribute listeners at
javax.servlet.http.HttpSessionAttributeListener? I used this to keep track of
session information e.g. users. Your "finalize" approach look much like the
attribute removal method. Cocoon 2 should use the methods of the Servlet 2.3
API as well, there is no need to re-invent the wheel.
