is an HTTP header included in requests, not responses.

DMM might begin to use this for checking country instead of cookies. If that will be the case, it will be impossible to manually console the DMM bypass.

You'll need a third-party application or extension to be able to manipulate request headers. Normal users will not be able to use devtools for it.

hopefully we get reports if it was really implemented or not
