Templating question?

Hi guys

Just looking for some advice really on how to best seperate different templates within CodeIgniter.

I know you can create as many views and controllers as you need and you can call these when needed, but I have a question regarding this.

Say I create a header view and controller how can I prevent this controller from being called directly from the URL, is there a built in method for doing this?

Thanks
