If you want to overwrite the status code (which you should not without a good reason),

set the ``X-Status-Code`` header::

If you want to overwrite the status code (which you shoulddonot without a good

This indeed will skip all checks that Symfony processes on setting response status code.

First check that Symfony does is fitting response status code.

Symfony leaves set status code as it is if it belongs to one of group:

If you do **not** set the ``X-Status-Code`` header, then Symfony uses the following

logic to determine the status code:

:method:`Symfony\\Component\\HttpFoundation\\Response::isClientError`

* If:method:`Symfony\\Component\\HttpFoundation\\Response::isClientError`,

:method:`Symfony\\Component\\HttpFoundation\\Response::isServerError` or

:method:`Symfony\\Component\\HttpFoundation\\Response::isRedirect` is true,

then the status code on your ``Response`` object is used;

:method:`Symfony\\Component\\HttpFoundation\\Response::isServerError`

* If the original exception implements

:class:`Symfony\\Component\\HttpKernel\\Exception\\HttpExceptionInterface`,

then ``getStatusCode()`` is called on the exception and used (the headers

from ``getHeaders()`` are also added);

:method:`Symfony\\Component\\HttpFoundation\\Response::isRedirect`

If status code is different then Symfony checks instance of raised Exception if it is

:class:`Symfony\\Component\\HttpKernel\\Exception\\HttpExceptionInterface` then its headers including status code are passed to response.

Otherwise status code 500 is set to response.

* If both of the above aren't true, then a 500 status code is used.
