      HttpResponse(entity = HttpEntity(ContentTypes.`application/json`, source))
    }
  }

val route =
  get {
    pathPrefix("special") {
      withSettings(special) {
        sample() // `special` file-io-dispatcher will be used to read the file
      }
    } ~ sample() // default file-io-dispatcher will be used to read the file
  }

// tests:
Post("/special/sample") ~> route ~> check {
  responseAs[String] shouldEqual s"{}"
}
Get("/sample") ~> route ~> check {
