How to decrease session time in cakephp?

There are several ways to decrease session time in CakePHP:

1. Update session configuration: In your CakePHP application, you can adjust the session timeout by editing the core.php file located in the app/Config directory. Look for the 'Session' configuration settings and update the 'timeout' value. For example, to set the session timeout to 15 minutes, you can use:

1
2
3
4

Configure::write('Session', [
    'defaults' => 'php',
    'timeout' => 15
]);

1. Use a shorter session ID: By default, CakePHP generates a session ID with a length of 32 characters. You can modify the session ID length in the core.php file by setting the 'ini' value of 'session.hash_length'. For example, to set the session ID length to 20 characters:

1
2
3
4
5
6
7

Configure::write('Session', [
    'defaults' => 'php',
    'timeout' => 15,
    'ini' => [
        'session.hash_length' => 20
    ]
]);

1. Regenerate session ID on each request: By regenerating the session ID on each request, you can prevent session hijacking and decrease session time. In your UsersController.php file, you can add the following code to regenerate the session ID:

1
2
3
4

public function beforeFilter()
{
    $this->Session->renew();
}

Please note that decreasing session time may impact the usability and functionality of your application. It is important to carefully consider the requirements and user experience before making any changes.
