few applications on the same server

Hello every body,

I used Code Igniter for a few applications on a server. Each application has its own codeigniter folder.

But I am not sure that the best practice in this case.

That I want is :
- some controllers and other ressources like pictures or js code are common for all app
- each app have its own config files (maybe on this point, I can match)

I think organization is better because controllers, models and views are not mixed in same folders but the code of codeigniter is replicated !


Have you some advices or good practices ?

In advance, I thank you.
