The ColdBox configuration CFC is the heart of your ColdBox application. It contains the initialization variables for your application and extra information used by third-party modules and ultimately how your application boots up. In itself, it is also an event listener or ColdBox Interceptor, so it can listen to life-cycle events of your application.
This CFC is instantiated by ColdBox and decorated at runtime so you can take advantage of some dependencies.
Controller : Reference to the main ColdBox Controller object (coldbox.system.web.Controller)
AppMapping : The location of the application on the web server
LogBoxConfig : A reference to a LogBox configuration object
Once the application starts up, a reference to the instantiated configuration CFC will be stored in the configuration settings with the key coldboxConfig. You can then retrieve it later in your handlers, interceptors, modules, etc.
Another cool concept for the Configuration CFC is that it is also registered as a ColdBox Interceptor once the application starts up automatically for you. Create functions that will listen to application events:
Note that the config CFC does not have the same variables mixed into it that a "normal" interceptor has. You can still access everything you need, but will need to get it from the controller in the variables scope.
