The request is first sent to the [url="http://ellislab.com/codeigniter/user-guide/overview/appflow.html"]Router[/url]. The Router examines the url and the request and handles it accordingly.

The reason for this is with CI's page caching function, upon a page request, the router will check if a cached paged exists and serve the static html without even running CI.
