How do you do a simple redirect?

[eluser]tomdelonge[/eluser]
I keep trying, but weird things happen.

Once it is supposed to redirect, it takes forever, and then the browser says:

The connection has timed out
The server at localhost.com is taking too long to respond.

But the weird thing is then the url in the address bar is the one I was trying to redirect to...

Is this not how to do it?: (I have the url helper loaded)

Code:

function testing()
    {
        if ( ! $this->session->userdata('logged_in'))
        {
             redirect('/admin/');
        }

    }
