> The Jetty Server for the framework REST API sets several HTTP headers for all
> responses. NiFi 2.2.0 changed the implementation from a Spring Security
> Filter to a Jetty Handler so that all responses would have these headers
> without having to pass through the Spring Security Filter Chain.
> The refactored approach did not include the
> [X-Content-Type-Options|https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/X-Content-Type-Options]
> header, which was present in earlier versions. The response header should be
> added to instruct clients to respect the response Content-Type header and
> avoid automatic type detection strategies.
