Izinkampani eziningi zokukhangisa abasebenzisa i-inthanethi ukunikela nokukhangisa ngemikhiqizo noma izinsizakalo zabo bavame ukusebenzisa inani elikhulu lamasu ukuphrinta abasebenzisi kulabo abafuna ukufinyelela, okungukuthi akukubi ngokusuka kulowo mbono, kepha ngenxa yokuhlukumezeka kwalokhu, izinkampani eziningi zokukhangisa zifuna ukuthola imininingwane ethe xaxa futhi ngaphezu kwakho konke ngokunemba ngangokunokwenzeka ngakho futhi kule ngxenye abasebenzisi abaningi akuzona ngokwabelana, ingasaphathwa eyokuthi igcinwe kumaseva wamanethiwekhi esikhangiso.
Esinye sezikhombi eziyinhloko esivame ukusetshenziswa yi-User-Agent, ekhombisa ngokuyisisekelo idatha yegama le-browser, inombolo yenguqulo yayo, igama kanye nohlobo lohlelo olusetshenzisiwe, phakathi kweminye imininingwane.
Kungakho kuzinkundla zeChromium, Abathuthukisi beChromium baphakamise ukuhlanganisa nokuqandisa okuqukethwe unhlokweni we-HTTP Umsebenzisi-Umenzeli, edlulisa igama nenguqulo yesiphequluli, kanye nokukhawulela ukufinyelela kwempahla ye-navigator.userAgent kuJavaScript.
Okwamanje alukho uhlelos ukususa unhlokweni woMenzeli-womsebenzisi okwamanje, kepha lolu hlelo seluhlongoziwe futhi luyaxhaswa futhi ngabathuthukisi be-Edge neFirefox futhi isivele isetshenzisiwe eSafari.
Esinye sezizathu eziyinhloko ukuhlanganisa ukususwa kweheda yomenzeli womsebenzisi ukusetshenziswa kwayo ekuthatheni izigxivizo zeminwe, kanye nomkhuba wokuphambanisa unhlokweni ngeziphequluli ezingathandwa kangako ukuqinisekisa ukusebenza kwamasayithi ngamanye (ngokwesibonelo, uVivaldi uphoqeleka ukwethula amasayithi afana ne-Chrome).
Ngesikhathi esifanayo, i-User-Agent eyimbumbulu kuziphequluli izinga lesibili futhi ivuselelwa yiGoogle uqobo, ngoba i-User-Agent ivimba ukungena kwezinsizakalo zayo.
Ubumbano futhi lukuvumela ukuthi ususe izintambo eziphelelwe yisikhathi nezingasho lutho zomsebenzisi we-User-Agent ezicacisa izimfanelo ezifana ne- "Mozilla / 5.0", "njengeGecko" ne- "like KHTML".
Unhlokweni woMsebenzisi-Umenzeli uphakanyiswa njengokufakwa esikhundleni se- indlela Amacebo Weklayenti Lomsebenzisi-Umsebenzisi, okubandakanya ukubuyiswa kokukhetha kwedatha kusiphequluli imingcele ethile nesistimu (inguqulo, ipulatifomu, njll.) kuphela ngemuva kwesicelo esivela kuseva nokunikeza abasebenzisi ikhono lokukhetha ngokunikezela ngolwazi olufanayo kubanikazi besayithi.
Lapho usebenzisa izinkomba zeklayenti lomenzeli womsebenzisi, isihlonzi asidluliswa ngokuzenzakalela ngaphandle kwesicelo esicacile, okwenza ukufakazela ubuqiniso kungenzeki (ngokuzenzakalela, igama lesiphequluli kuphela elishiwoyo).
Mayelana nokuhlonza okusebenzayo, imininingwane eyengeziwe enikezwe ukuphendula isicelo incike kuzilungiselelo zesiphequluli (isibonelo, umsebenzisi anganqaba ukudlulisa idatha) futhi izimfanelo ezidlulisiwe zimboza inani elifanayo lolwazi njengeyunithi yezinhlamvu yomenzeli womsebenzisi yamanje.
Umthamo wedatha edlulisiwe ungaphansi komkhawulo wobumfihlo, enquma umkhawulo wenani ledatha elingasetshenziselwa ukuhlonza; Uma imininingwane engaphezulu ingaholela ekwephulweni kokungaziwa, okunye ukufinyelela kuma-API athile kuyavalwa.
Ubuchwepheshe buvela njengengxenye yesinyathelo sobumfihlo seSandbox okuthunyelwe ngaphambilini kuhloswe ukufeza ukuvumelana phakathi kwesidingo sabasebenzisi sokugcina imfihlo kanye nesifiso samanethiwekhi esikhangiso namasayithi wokulandelela okuthandwa yizivakashi.
Ngokwecebo lamanje, ukufinyelela kwempahla i-navigator.userAgent izokwehliswa ku-Chrome 81 (kuhlelelwe uMashi 17).
I-Chrome 81 izoyeka ukubuyekeza inguqulo yesiphequluli futhi izohlanganisa izinguqulo zohlelo lokusebenza futhi i-Chrome 85 izohlanganisa umugqa nesihlonzi sohlelo lokusebenza (Kuzokwenzeka kuphela ukunquma ideskithophu nesistimu yokusebenza yeselula, nangezinhlobo zamaselula, kuzonikezwa imininingwane ngosayizi ojwayelekile wedivayisi.
Uma ufuna ukwazi kabanzi mayelana nengxoxo ebibanjelwe kwizithangami zeChromium, ungabonisana nayo Kulesi sixhumanisi esilandelayo.
