Is it possible to make two different sites with the same application folder but with own index files and controller folders?
For example with such structure:
I want to use the same configs, models etc but the different controllers and routes. The site1 controllers/routes should not be available for site2, and the site2 controllers/routes for site1.
It is not possible to share individual files in both apps (maybe other then some symlink magic).
You can solve that with modules and packages, which can be shared without problems. The same is true btw for the core, you can have a server full of apps, all sharing the same core folder.
