I have found various posts about instance variables, session variables
and parameters (each of which seems to use differnet syntax and have
different view on the "best practice") I would like to find a single,
reliable source that provides a good overview on all of it.

Specifically, I would like to learn how to pass parameters between
controllers and how to set session variables so they can be seen from
any Controller/Model.

Thanks
