With this method, possibly create a simple response by current Accept header

trait MyController extends BaseController with RespondToSupport {
  import HttpService._ // !!!important, because macro expand with methods from this namespace
  def index = {
    respondTo {
      case `text/html` => "html response"
      case `application/json` if this_ajax_request => "json response"
    }
  }
}

//And then request with Accept: `text/html` we get a "html response"
//And when request with Accept: `application/json` and wit ajax, we get a "json response"
//Otherwise get Error: 406 Not Acceptable

val header = request.headers.find(_.name == "Accept") //request from BaseController
header match {
   case Some(header) =>
      val h = header.value
      h match {
        case value if h.contains(`media/type`.value) && you_guard =>
          respondWithMediaType(`media/type`) {
            complete { you_response } // from previous: it's a "html response" or "json response"
          }
