    }
    else
    {
        // Serve the file to the client
        result = Request.CreateResponse(HttpStatusCode.OK);

        result.Content.Headers.ContentDisposition = new System.Net.Http.Headers.ContentDispositionHeaderValue("attachment");
        result.Content.Headers.ContentDisposition.FileName = "SampleImg";
