Does anybody have a clue why would header() function work, while CI's redirect() is throwing a blank page. I have observerd it across various controllers. I even tested this right in my main controller, at the very beginning of the code.
Checked logs and error reporting with no result. I am almost 100% sure that nothing is showing up before the headers...

This is my main controller

Code:
&lt;?php if (!defined('BASEPATH')) exit('No direct script access allowed');

define('HOST1', $_SERVER['HTTP_HOST']);

define('LOGO', 'http://img1.domain.com/logo/logo_v1_bg.gif');

class  MY_Controller extends Controller{

    function __construct(){

        parent::__construct();

        $this->setup_assets();

    }

    function setup_assets(){

            //$this->output->enable_profiler(TRUE);

            //$this->benchmark->mark('my_controller_start');

        if(!isset($this->data['url_array'])) $this->data['url_array'] = $this->uri->uri_to_assoc(2);

        //redirect for deleted categories

        $this->data['controller'] = $this->uri->segment(1);

                $redirect_cat_array=array(

                    105=>199,

                    106=>199,

                    210=>299,

                    408=>499,

                    503=>502,

                    504=>502,

                    505=>502,

                    705=>799,

                    806=>899,

                    907=>999,

                    1008=>1099,

                    1108=>1199,

                    1209=>1299,

                    1608=>1699,

                    1609=>1699,

                    1305=>1399,

                    1306=>1399

                );

        if( isset($this->data['url_array']['catid']) && isset($redirect_cat_array[$this->data['url_array']['catid']]) ){

            $redirect_link = str_replace('catid/'.$this->data['url_array']['catid'],'catid/'.$redirect_cat_array[$this->data['url_array']['catid']],$_SERVER['REQUEST_URI']);

            //redirect($redirect_link);

                        header("Location:".$redirect_link,TRUE,301);

        }

NOtice above I comented out the redirect() function, because if I enable it and remove header function - I will get a blank page.

Are there any errors showing up? Check your CodeIgniter logs to see if anything nuts is happening.

Where are you loading url_helper?

No errors show up, CI logs are empty (yeah - I try to keep on top of all the little issues and errors, so the logs usually are clean)
URL helper is loaded with autoload
What I can't get my head around is WHY is header() working and not redirect()? Are they not same behavior?
Is there a way to trace whats happeneing:

By the way, I did PAGE SOURCE for the blank page and this is what I see:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML><HEAD>
<META http-equiv=Content-Type content="text/html; charset=utf-8">
<META content=CMVRDPEJHO name=SKYPE_FRAMEID></HEAD>
<BODY></BODY></HTML>

what do you get if you echo out

Code:
$redirect_link

?

Unfortunatly redirect() does not work even if the link is hardcoded, such as:

Code:
redirect('account/logout');

Thanks for the suggestion :-S

what type of server are you using (linux, windows, mac, etc)?

have you tried setting the second optional parameter?

Code:
redirect($redirect_link, 'refresh'); // if using Windows, the 'refresh' is needed

also, I see you are setting the header to a 301 redirect. Why not set the redirect to the same thing?

Code:
redirect($redirect_link, 'refresh', 301);

//or

redirect($redirect_link, 'location', 301); //may be faster, but don't use on a Windows server

That did it for me.
I was starting a new project and completely forgot to autoload this helper !
