Config setting
We will configure prefix in config.php file on “application/config” directory. if you want to keep custom prefix different name then you can. This item allows you to set the filename/classname prefix when extending.
$config['subclass_prefix'] = 'MY_';
So, we will create MY_Output.php file on “application/core” directory. after then paste the below code in this file.
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class MY_Output extends CI_Output {
function nocache()
{
$this->output->set_header("HTTP/1.0 200 OK");
$this->output->set_header("HTTP/1.1 200 OK");
$this->output->set_header('Last-Modified: '.gmdate('D, d M Y H:i:s', $last_update).' GMT');
$this->output->set_header("Cache-Control: no-store, no-cache, must-revalidate");
$this->output->set_header("Cache-Control: post-check=0, pre-check=0");
$this->output->set_header("Pragma: no-cache");
}
}
