addExposedHeaders(response: Response): Response
If the list of exposed headers is not empty add one or more Access-Control-Expose- Headers headers, with as values the header field names given in the list of exposed headers.
If the list of exposed headers is not empty add one or more Access-Control-Expose- Headers headers, with as values the header field names given in the list of exposed headers.
By not adding the appropriate headers resource can also clear the preflight result cache of all entries where origin is a case-sensitive match for the value of the Origin header and url is a case-sensitive match for the URL of the resource.

apply(request: Request, service: Service[Request, Response]): Future[Response]
Fully handle preflight requests.

Resources that wish to enable themselves to be shared with multiple Origins but do not respond uniformly with "*" must in practice generate the Access-Control-Allow-Origin header dynamically in response to every request they wish to allow. As a consequence, authors of such resources should send a Vary: Origin HTTP header or provide other appropriate control directives to prevent caching of such responses, which may be inaccurate if re-used across- origins.
