Subject: [PATCH] prevent IE from interpreting HTML MIME type
Date: Sun, 03 Dec 2017 18:10:47 +0100
Message-ID: <20171203181047.01d078d5.peter.mueller@link38.eu>
MIME-Version: 1.0
Content-Type: multipart/mixed; boundary="===============2371166543646099679=="
List-Id: <development.lists.ipfire.org>

--===============2371166543646099679==
Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: quoted-printable

Add X-Content-Type-Options header to prevent Internet Explorer
from interpreting the MIME type of a server answer on its own,
which could lead to security risks.
