```php
use Slim\Psr7\Response as R;
use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;
/**
* Login page
*
* @param Request $request ServerRequestInterface
* @param Response $response ResponseInterface.
*/
public function login(Request $request, Response $response): Response
{
$r = new R();
$r->withHeader('Location', 'http://localhost');
dump($r);
dd($r->getHeaders());
...
}
```
```php
^ Slim\Psr7\Response {#423 ▼
#status: 200
#reasonPhrase: ""
#protocolVersion: "1.1"
#headers: Slim\Psr7\Headers {#424 ▼
#globals: []
#headers: []
}
#body: Slim\Psr7\Stream {#425 ▼
#stream: stream resource @508 ▶}
#meta: null
#readable: null
#writable: null
#seekable: null
#size: null
#isPipe: null
#finished: false
#cache: null
}
}
```
```auto
[]
```
Why headers are empty for new response ?
Real code example, is that I am using redirect() helper inside method login() and it is not works because new response headers are empty for some reason.
```auto
"slim/slim": "^4.8.1",
"slim/psr7": "^1.4",
```

```php
function redirect(string $routeName, array $data = [], array $queryParams = []): Response
{
$response = new Response();
$response->withHeader('Location', urlFor($routeName, $data, $queryParams));
$response->getBody()->write("Hello");
return $response;
}
```
Added for test and it works
```php
$response->getBody()->write("Hello");
```
but `$response->withHeader` is not.

The headers are immutable. This should work:
```php
$response = $response->withHeader('Location', 'new url');
```

Yes this is also correct in this context. It just returns the new instance directly.
