In a servlet J2EE application, there is an init style method that gets called after that servlet is loaded. Is there something similar within a rails controller context. I am looking for something where I can load and setup a particular object. Also, what about with sessions as well. I would like to call some library when a user session begins and possibly kill that object when the session ends. – Berlin B.

Sessions are usually automatically created on Rails, by default, upon first access. So it seems doubtful that there is a special callback, since they are “nothing special”. However, you can easily setup a global method (through ApplicationController) that would setup/teardown session, something like start\_session/end\_session.
