Another amended version - I was trying to download a zip file as binary content and this is what worked for me -

  def byte_range_response (request, response, content)
    file_begin = 0
    file_size = content.bytesize
    file_end = file_size - 1

    status_code = '206 Partial Content'
    match = request.headers['range'].match(/bytes=(\d+)-(\d*)/)
    if match
      file_begin = match[1]
      file_end = match[2] if match[2] && !match[2].empty?
    end
    content_length = file_end.to_i - file_begin.to_i + 1
    response.header['Content-Range'] = 'bytes ' + file_begin.to_s + '-' + file_end.to_s + '/' + file_size.to_s
    response.header['Content-Length'] = content_length.to_s
    response.header['Cache-Control'] = 'public, must-revalidate, max-age=0'
    response.header['Pragma'] = 'no-cache'
    response.header['Accept-Ranges']= 'bytes'
    response.header['Content-Transfer-Encoding'] = 'binary'
    send_data get_partial_content(content, content_length, file_begin.to_i), type: 'application/octet-stream', status: status_code
  end

  def get_partial_content(content, content_length, offset)
    test_file = Tempfile.new(['test-file', '.zip'])
    test_file.puts(content)
    partial_content = IO.binread(test_file.path, content_length, offset)
    test_file.close
    test_file.unlink
    partial_content
  end
