Mgbe a na-ekwurịta okwu Google iji jikọta ọdịnaya nke isi ihe HTTP User-Agent, onye nrụpụta ihe nchọgharị Kiwi gaa na "X-Client-Data" HTTP nkụnye eji isi mee nke fọdụrụ na Chrome, nke nwere ike Iwu nchekwa data izugbe na-arụ ọrụ na European Union ().

Ihe nkụnye eji isi mee X-Client-Data abụghị ọrụ ezoro ezo yana omume ya bụ na akwụkwọ.
