there's nothing wrong with using cookie to remember language choice

if you don't want to do the check in every controlller, you could create MY_Controller in application/libraries. Then you can put your lang check in the constructor of that controller.

All of your other controllers can then extend MY_Controller rather than Controller

search the forums or the user guide for extending controllers and I hope that helps you!

Use the pre_controller HOOK, no MY_Controller needed.
