How to serve file download with resume capability in Play Framework 2?

I had used this route:

GET         /assets/*file           controllers.Assets.at(path="/public", file)

and this action:

public static Result downloadFile(String filePath) {
    File file = new File("public/files/"+filePath);
    return ok(file);
}

But they did not work.

I don't think play provides resumable downloads out of the box, but it is probably easy to implement it by yourself. Take a look here to see which HTTP headers you should use:
