def force_header(header, value):

    ''''Decorator that forces a header in the response to have a specific value.
    Usage:

    The HeaderControlMiddleware must be used and placed as closely as possible to the top
    of the middleware chain, ideally after any caching middleware but before everything else.
    This decorator is not safe for multiple uses: each call will overwrite any previously set values.'
