Why Flashdata value gets null on redirecting to another function in Codeigniter?

I am trying to get the input values from the view to controller and saving this value as flashdata to use it in the other controller. Now the i am able to store the value until i redirect, but as soon as it comes to redirect, it loses its value. I am not sure whats going over here.

Here is my code below:-

Controller.php

public function first() { 
 $testing = $this->input->post('fname');
 $this->session->set_flashdata('fstname', $testing);
 $this->session->keep_flashdata('fstname');
 // echo $this->session->flashdata('fstname'); //able to get the flashdata value till here. 
 redirect('Home/second/'); //but when I am using this, flashdata loses its value
}

public function second() { 
 $data['getfname'] = $this->session->flashdata('fstname');
 $this->load->view('details', $data);
}

View (details.php)

 <?php echo $getfname ?>

Output

Null

config.php

$config['sess_driver'] = 'files'; 
$config['sess_cookie_name'] = 'ci_session'; 
$config['sess_expiration'] = 7200; 
$config['sess_save_path'] = APPPATH . 'cache/sessions/'; 
$config['sess_match_ip'] = FALSE; 
$config['sess_time_to_update'] = 300; 
$config['sess_regenerate_destroy'] = FALSE;

autoload.php

$autoload['libraries']=array();

Additionally, I also tried using userdata() but its not showing on the second function after redirect.

Thanks for your time.

First:

check if Post data is not empty

$testing = $this->input->post('fname');
var_dump($testing);
exit;

Second:

you can skip keep_flashdata, you dont need that in that context

Third:

Check session setting in config.php for example:

$config['sess_driver']          = 'database';
$config['sess_cookie_name']        = 'mysession';
$config['sess_expiration']         = 86400;
$config['sess_save_path']          = 'sessions';
$config['sess_match_ip']           = TRUE;
$config['sess_time_to_update']     = 300;
$config['sess_regenerate_destroy'] = TRUE;

check autload.php: $autoload['libraries'] = array('session', [...]);

Fourth:

check session flash var directly:

$strFstname = $this->session->flashdata('fstname');
die($strFstname);

Your code should work, I used flashdata like this many times.
