Laravel子域丢失重定向会话

I use subdomain wildcards to create user specific pages for example {slug}.mysite.com

Users might navigate from mysite.com to {slug}.mysite.com

However I seem to have different login sessions for these two routes / domains.

Route::group(['domain' => '{slug}.mysite.com'], function()
{
    Route::get('/', 'PagesController@showByUsername');

    Route::get('/plans/{plan}', 'PlansController@showslug');

    Route::controllers([
        'auth' => 'Auth\AuthControllerClient'
    ]);
});

This is because cookies are specific to subdomain.

This is from config/session.php

/*
|--------------------------------------------------------------------------
| Session Cookie Domain
|--------------------------------------------------------------------------
|
| Here you may change the domain of the cookie used to identify a session
| in your application. This will determine which domains the cookie is
| available to in your application. A sensible default has been set.
|
*/

'domain' => null,

You will need to set this value to something which will include all of your subdomains.
