more thoughts: could I do something like:
- define a shared global variable session.version - = -1 initially, signifying no choice made - ? use a callback that gets executed *before *the controller that responds to the request - if session.version >-1: let the responding controller do its thing else: if controller allowed to run: let the controller run else: redirect to 'please choose version' Is it possible to implement such a "callback"??? (or is this not the right/best way to achieve the functionality I need?) thanks, Luis.
