I’m reading doc of Slin4 and I trying do this -
$response = new Response();
$response-\>withHeader(‘Location’, ‘[https://www.example.com](https://www.example.com)’);
print\_r($response-\>getHeaders());
But it print nothing. I try googling and i didn’t understand what is wrong

The PSR-7 request and response headers are “immutable”. So try this:
```auto
$response = $response->withHeader('Location', 'https://www.example.com');
```

Hmmm, it is working! Thank you. I’m in deep shock. This method gives back the whole object of response?

Yes, it creates a “clone”, changes or adds the new value and returns the cloned object.
