Redirect Help

Because it may be useful, in addition to the redirect() issue(s), the cookie helper seems to be borked.

Doesn't matter if I put this in a Controller or a Model, it does nothing that I can find, and does not throw any errors.

Code:

helper('cookie');
set_cookie('testcookie','testdata');
$c = get_cookie('testcookie');
print_r($c);

And there is no cookie set in my browser.

Could this be an installation problem?
Most everything that I've used in this installation works as expected, but not redirect() or the cookie helper.

Thanks, again.
