Multiple domains pointing to same CI application

Thanks for all the replies.

But those steps above still doesn't allow the site to choose different databases based on the domain.

What I mean is that all the controllers, models, and views will be shared by all the different domains. The only thing that is different is the database that would be called based on each domain. For example, if someone goes to http://www.NewYorkSite.com, then the site would use the New York database. If someone goes to http://www.DetroitSite.com, then the site would use the Detroit databse. But they will all share the same controllers, views, models, etc, just different database.

Now, what I was asking is if there is a way to just use different databases based on the domain?
