Multiple websites on 1 CI install

[eluser]Unknown[/eluser]
Hi all,

I'm new to CI and have a question.

I have a server with multiple domains and websites and was wondering if it is possible to install CI only once and use it for all my application.

I was thinking of putting the CI installation in my include path, but how can I link my application to this system folder.

For every application I create I want to add the folders I need and use in the application folder, such as cotroller / views / models.

Is this possible?

Thanks in advance.
