Answer 1

$config['sess_cookie_name'] = 'myvalue';

In config.php file you can set the same value on both CI Apps., with 'file' Session Drivers

CI_Session Object

( [userdata] => Array ( [__ci_last_regenerate] => 1490351129 [Level] => 1 [User] => 103 [Fullname] => Ruben Caldera )

[_driver:protected] => files
[_config:protected] => Array
    (
        [cookie_lifetime] => 600
        [cookie_name] => MyHiddenValue
        [cookie_path] => /
        [cookie_domain] => 
        [cookie_secure] => 
        [expiration] => 600
        [match_ip] => 
        [save_path] => /tmp
    )

)
