Headers set to no cache are not honored?

[eluser]drewbee[/eluser]
I just stumbled upon something very interesting. It turns out my headers are being set by this function EXCEPT when accessing the default controller / method. I was always testing on the default controller / method, hence why I thought they were never being set.

Can someone please verify this for me?

To do:
1. Set a noticeable header with CI's $this->output->header() function.
2. Access yoursite.com (forcing it to use default controller/method)
- Is the header present?
3. Access yoursite.com/defaultcontroller/defaultmethod.html
- Is the header present?

For me 2 = no, and 3 = yes.
