Redirect in php throws 520 error CloudFlare

I am using cloudflare with codeigniter framework and I am facing strange problem while trying to redirect the script to another page when the action is completed, server use to throw error 520(cloudflare server)

$input = $this->input->post();

if(!empty($input)){

        $this->load->library('form_validation');

        $this->form_validation->set_rules('email', 'Email', 'required|email');
        $this->form_validation->set_rules('password', 'Password', 'required');

        if ($this->form_validation->run() == TRUE)
        {
            $r = $this->userModel->login($input["email"], $input["password"]);
            if($r["success"] == "t"){

                $this->userModel->setSession($r["_user_id"], $r["token"]);

                //Both redirect methods does not works
                //echo '<html><head><META http-equiv="refresh" content="0;URL='.$this->glob->exec_redirect().'"></head><body></body></html>';
                redirect($this->glob->exec_redirect());
                die();
            }else{
                $data["errors"] = $r["message"];
            }
        }else
            $data["errors"] = validation_errors();
    }
    $this->load->view("user/login", $data);

This script work fine without cloudflare, also the script work fine with cloudflare without redirect functions. Demos:

Sample which throws error

user: test

pass: test12

Sometimes you should try more then once to crash

Sample without redirect

Works fine, user is logged in just have to redirect Manuel.

Are you doing anything that sends large cookies or headers? That's a possible cause & support can help troubleshoot.

I logged in, and it worked. Then, I logged out and tried to login again and I saw the 520 error you're talking about.

I think it has something to do with your redirect URL.

https://www.plac24.com/user/login?rdr=http%3A%2F%2Fwww.plac24.com%2F

As you're redirecting them to your website, do you need the http://?
