Cookie domain refers to the list of domain names or subdomain names available for Cookies. For example, if you set a cookie for the ".example.com" domain, the cookie can be used under any subdomain of example.com, such as blog.example.com and shop.example.com.

Set Cookie Domain in Laravel

In Laravel, you can use the cookie global helper and the withCookie method to set the application's Cookie domain .

To set the cookie domain, use the cookie global assistant to set a new cookie, including the domain name you want to use:

$response = response('Hello World')->cookie(
    'name', 'value', $minutes, '/', '.example.com', false, true

return response('Hello World')->withCookie($cookie);

return response('Hello World')->withCookie($cookie1, $cookie2, $cookie3);

$cookie = cookie('name', 'value', 60);
return response('Hello World')->withCookie($cookie);

The above code will set a cookie named "name" with a value of "value" and an expiration time of 60 minutes under the current domain name.

If you want to limit the cookie domain to the current root domain name, you can use:
