You can find it in the directory ress_cookie_wurfl with the class Ress_Cookie_Wurfl in app.php. I added a generalized apploader to bootstrap.php. The Apploader (application loader) in this case is just a function in bootstrap.php that takes the module name as an argument and returns a module class instance.
