Lokacin da albarkatun shafi ɗaya ɗaya ke buƙatar wuraren ƙarshe daban-daban, yi amfani da rubutun execute kuma yi rajistar zaɓin kafin kewayawa:

function main(splash, args)
  splash:on_request(function(request)
    local host = args.default_proxy
    if request.url == args.special_resource then
      host = args.special_proxy
    end
    request:set_proxy{host = host, port = 8080, type = 'HTTP'}
  end)

  assert(splash:go(args.url))
  return splash:html()
