I have a controller, that when it is finished doing it’s thing, should
always redirect back to the controller that called it. Is there any
built-in way to access who the referring controller was?
A controller calls ControllerB
ControllerB does it’s thing and should be able to redirect back to the
previous controller, whether it is ControllerA or ControllerC, without
know who it was.
Is there any default way to do this? Seems like variable with the
referring controller and action would be pretty handy.
