Disabling the Bootstrap File and Class Caching

And to make the production environment as fast as possible, Symfony creates

because the same class can be located in two different places: the original class

file and the big file which aggregates lots of classes.

This recipe shows you how you can tweak this caching mechanism to make it friendlier

when you need to debug code that involves Symfony classes.
