-Presuming the script files use the `.js` or `.mjs` extension, and
-the stylesheets `.css`, Apache can be configured to serve the with
-the `X-Content-Type-Options` header with the value of `nosniff`
-using the [`Header` directive][header directive]:
-
-```apache
-<IfModule mod_headers.c>
-     <FilesMatch "\.(css|m?js)$">
-        Header set X-Content-Type-Options "nosniff"
-    </FilesMatch>
-</IfModule>
-```
-
-Note that:
-
-* The above snippet works with Apache `v2.2.0+`, but you need to have
-  [`mod_headers`][mod_headers] [enabled][how to enable apache modules]
-  in order for it to take effect.
-
-* If you have access to the [main Apache configuration file][main
-  apache conf file] (usually called `httpd.conf`), you should add
-  the logic in, for example, a [`<Directory>`][apache directory]
-  section in that file. This is usually the recommended way as
-  [using `.htaccess` files slows down][htaccess is slow] Apache!
-
-  If you don't have access to the main configuration file (quite
-  common with hosting services), just add the snippets in a `.htaccess`
-  file in the root of the web site/app.

-Presuming the script files are sent with the `Content-Type` header set
-to `text/javascript` and styleshees to `text/css` you can use
-a [`URL rewrite` rule][url rewrite] like the following:
-
-```xml
-<configuration>
-     <system.webServer>
-        <rewrite>
-            <outboundRules>
-                <!-- Add X-Content-Type-Options header to text/javascript
-                     and text/css responses -->
-                <rule name="X-Content-Type-Options" enabled="true">
-                    <match serverVariable="RESPONSE_X_Content_Type_Options" pattern=".*" />
-                    <conditions>
-                        <add input="{RESPONSE_Content_Type}" pattern="text\/(javascript|css)" />
-                    </conditions>
-                    <action type="Rewrite" value="nosniff"/>
-                </rule>
