Sharing session with no CI app

Hi guys!
I´m having a hard time trying to share the same session between a native php app and a ci app the situation is the next:
We are currently trying to migrate an entire app to CI4
the native php app produce a session and at some time make a post to CI app when i land to the CI app (works great) the session does not pass to CI
im playing with the session files cause i think it search for the same ci_session name i already change the both sessions names to try to mach eachother (with no luck)
the session file that the old app is creating, got the name: sess_d5agcbecpo9jhq8951g59g67na
meanwhile when the app lands at ci this produce this file: mhp_session2ag2pf95sto44ukte3huptrt1gnap3k5  (mhp_session is my cookie_name in .env file)
Session are created anew.

Tip: when i click back in explorer it produce another session file with this name: sess_d5agcbecpo9jhq8951g59g67na (with no data and crash the sistem)

Another Tip in ci app im using session service from CI4 in my BaseController

Code:

$this->session = \Config\Services::session();

Thanks in advance!

check your CI session driver, default is FileHandler (store in writable folder)

I have my BaseController like this for checking session.

PHP Code:

<?php

namespace App\Controllers;

use CodeIgniter\Controller;
use CodeIgniter\HTTP\CLIRequest;
use CodeIgniter\HTTP\IncomingRequest;
use CodeIgniter\HTTP\RequestInterface;
use CodeIgniter\HTTP\ResponseInterface;
use Config\Services;
use Psr\Log\LoggerInterface;

 /**

 protected $session;

 protected static $globalViewData = [
 'test' => 'This works!',
 ];

    /**

    public function initController(RequestInterface $request, ResponseInterface $response, LoggerInterface $logger)
    {
     // Do Not Edit This Line
     parent::initController($request, $response, $logger);

     // Preload any models, libraries, etc, here.

     // E.g.: $this->session = \Config\Services::session();

     // Ensure that the session is started and running
     if (session_status() == PHP_SESSION_NONE)

 protected function mergeGlobalData(array $viewData) : array
 {

 {

Make sure you do the session check to see if it is loaded first.

Hi boyos! 
first of all thks for the response!
now... i tried the session check first in my base controller -> didnt work... its still creating a new session file in writable/session folder i change my .env to try and match the name of my session with the other app like this:

Code:

app.sessionDriver = 'CodeIgniter\Session\Handlers\FileHandler'
app.sessionCookieName = 'sess'

the result is: a session file named sess_aj2fri8h0ucnsfu5shkjhmmtaj -> my app session
sess7mo31q37chk4ghtbkjl81i8ruhlg2id7 my ci session if i putt the sessionCookieName = 'sess_' generates a session with the name "sess_" diferente to the other app named "sess", gives me two session diferents names....

Im using filehnadler, the two sessions are stored in writable/session folder
Salute!

Best bet would be to store the information in the database. Sharing session data would be a security risk.
