title: Laravel Auth between subdomains Only Works With Remember Me
body: <p>In Laravel 5.7, I have the following middleware:</p>
  
  <pre><code>  public function handle($request, Closure $next)
  {
      if (!\Auth::check())
      {
          return response("Not logged in!", 500);
      }
      return $next($request);
  }
  </code></pre>
  
  <p>This works well when remember me is checked, but not when it was not checked AND the request is going to a different subdomain.  If I check remember me, it works well.  So the request goes from www.mysite.com to api.mysite.com.  The only time there are issues is again, when remember me is not checked.  </p>
  
  <p>For SESSION_DOMAIN I have .mysite.com and SESSION_SECURE_COOKIE=true.</p>
  
  <p>Any ideas?</p>
