the parameter that configures the cache folder is in <code>config.php</code> and its called <code>cache_path</code>. For modifying in during runtime, we can use the <code>$this-&gt;config-&gt;set_item</code> function. Obviously, the cache folder switch should be done as early as possible in the controller function, before the caching function call.

Here is a sample implementation, controller <code>Test</code>:

<pre><code>&lt;?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Test extends CI_Controller {

 /**
 * Index Page for this controller.
 *
 * Maps to the following URL
 * http://example.com/index.php/welcome
 * - or -
 * http://example.com/index.php/welcome/index
 * - or -
 * Since this controller is set as the default controller in
 * config/routes.php, it's displayed at http://example.com/
 *
 * So any other public methods not prefixed with an underscore will
 * map to /index.php/welcome/&lt;method_name&gt;
 * @see https://codeigniter.com/user_guide/general/urls.html
 */
 public function index()
 {
 $user_language = 'french';

 $this-&gt;config-&gt;set_item('cache_path', 'IS_ROOT/cache/' . $user_language . '/');

 $this-&gt;output-&gt;cache(1);

 $this-&gt;load-&gt;view('welcome_message');
 }
}
</code></pre>

when you run it, you can see in the logs, that the directory "french" under the "global" IS_ROOT/cache was used:

<pre><code>INFO - 2018-06-09 22:12:39 --&gt; File loaded: /php_basedir/CodeIgniter_3_1_8/application/views/welcome_message.php

I Find a solution. we must edit <code>output.php</code> in core folder like this.

<pre><code> public function _write_cache($output){
 $CI =&amp; get_instance();
 $lang = $CI-&gt;session-&gt;userdata('language');
 $path = $CI-&gt;config-&gt;item('cache_path');
 $cache_path = ($path === '') ? APPPATH.'cache_'.$lang.'/' : $path;
 //other code
 }
 public function _display_cache(&amp;$CFG, &amp;$URI){
 $CI =&amp; get_instance();
 $lang = $CI-&gt;session-&gt;userdata('language');
 $cache_path = ($CFG-&gt;item('cache_path') === '') ? APPPATH.'cache_'.$lang.'/' : $CFG-&gt;item('cache_path');
 //other code
 }
</code></pre>

I have a multiple language website I want to create a specific cache folder for every language. How Can I do this?
I currently using one cache folder with this code.

Can You Help Me?

<pre><code>$lang = $CI-&gt;session-&gt;userdata('language');
$cache_path .= md5($uri).'-'.$lang;
</code></pre>
