Headers set to no cache are not honored?

headers with standard PHP header()

HTTP/1.x 200 OK

Server: Apache/2.2.11 (Unix) mod_ssl/2.2.11 OpenSSL/0.9.8i DAV/2 FrontPage/5.0.2.2635 mod_bwlimited/1.4 mod_auth_passthrough/2.1

And with CI's header function

HTTP/1.x 200 OK

So this confirms my headers are not being set.

I just dug into the base Codeigniter.php file, and for some reason, call_user_func_array() cleans out the output class var. ????

Line 230-233

Code:

echo print_r($OUT);
        // Call the requested method.
        // Any URI segments present (besides the class/function) will be passed to the method for convenience
        call_user_func_array(array(&$CI, $method), array_slice($URI->rsegments, 2));

Outputs:

Code:

CI_Output Object ( [final_output] => [cache_expiration] => 0 [headers] => Array ( [0] => Array ( [0] => Last-Modified: Wed, 1 Apr 2009 18:16:28 GMT [1] => 1 ) [1] => Array ( [0] => Expires: Wed, 1 Apr 2009 18:16:28 GMT [1] => 1 ) [2] => Array ( [0] => Cache-Control: no-store, no-cache, must-revalidate [1] => 1 ) [3] => Array ( [0] => Cache-Control: post-check=0, pre-check=0 [1] => ) [4] => Array ( [0] => Pragma: no-cache [1] => 1 ) ) [enable_profiler] => ) 1

But the following (moved print_r below the function call):

Code:

// Call the requested method.
        // Any URI segments present (besides the class/function) will be passed to the method for convenience
        call_user_func_array(array(&$CI, $method), array_slice($URI->rsegments, 2));
                echo print_r($OUT);

Outputs : [empty string] The var is defined, as it doesn't throw any errors; Which makes me think $OUT->_display() doesn't get called. Yet none of my crap would show up if this was not true.

I am officially bewildered to no end.

My template draw() method...

Code:

function draw($data = null)
    {
        $data = array('data'         => $data,
                      'page'         => $this->page);
        $this->CI->load->view('global_template', $data);
    }

The only thing different I see going on here, is that the global template.php file is the one that calls $this->load->view() for all pages within itself. As a test, I simply loaded a base view from draw(). Same effect. I'm not missing some function call that I need to for final rendering of the output class am i? Using $this->CI->output->get_output(); from my template class I ended up with everything doubled.

WTF? lol.
