Hello.

I have created MR for these changes.
Documentation here:
https://github.com/symfony/http-foundation/blob/6.3/Request.php#L1126C38...
https://api.hostdog.eu/api/drupal-9/drupal%21core%21vendor%21symfony%21h...

Thanks! LGTM and ->getHost() seems correct. Now we please need some people for community testing.

Alternative might be $request->server->get('HTTP_HOST');

Rebased. If someone tests this and can confirm it works as expected, we can merge this. The tests are green now.

Tested and works as expected, thank you! :)
