[HELP] Cache system frustrating me?

[eluser]howler[/eluser]
I change this:

Code:

function index()
    {
        $this->output->cache(0);
        print "ge2";
        $this->load->view('welcome_message');
        }

to:

Code:

function index()
    {
        $this->output->cache(0);
        print "ge5";
        $this->load->view('welcome_message');
        }

Yet, the welcome page still shows the "ge2" print. The "Page rendered in 0.0147 seconds" updates with a different time each time I refresh the page.

Deleting the cache doesn't effect it. If I spam 'reload', after a while, it will update the page.
What's going on?
