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.
