Redirect From Model To View [MVC]

Hi,

I'm running a small MVC model for a one page website, it runs in the following order:
1. User type http://www.online.com/library
2. The htaccess file redirect this url to http://www.online.com/library/controller.php?action=list
3. The controller file checks for the action query, list all the data in a session variable and use php header("Location:...) to redirect to the view
4. The View list all the data from the session variable.

My only concern with this scenario is that the user ends up with http://www.online.com/library/view.php in his address bar so he thinks it's the same as browsing to "/library/". What i want to accomplish now is making a redirect from the controller to the view without informing the client, so ends up with the same "/library/" in his address bar.

Thanks In Advance
Regards.
