Abaphuhlisi beChromium ukudibanisa kunye nokumisa kwiinguqu kwimixholo ye-User-Agent HTTP header, ehambisa igama kunye noguqulelo lwesikhangeli, kunye nokukhawulela ukufikelela kwipropathi ye-navigator.userAgent kwiJavaScript. Susa i-header yoMsebenzisi-Ayinti okwangoku . Eli phulo sele lixhaswe ngabaphuhlisi ΠΈ , kwaye sele iphunyeziwe kwi Safari.
Njengoko kucwangcisiwe ngoku, i-Chrome 81, ehlelelwe i-17 kaMatshi, iya kuhoxisa ukufikelela kwipropati
navigator.userAgent, iChrome 81 iyakuyeka ukuhlaziya uguqulelo lwesikhangeli kwaye idibanise iinguqulelo zendlela yokusebenza, kwaye
IChrome 85 izakuba nomgca odityanisiweyo kunye nesichongi senkqubo yokusebenza (kuyakwenzeka kuphela ukumisela idesktop kunye ne-OS ephathwayo, kunye neenguqulelo eziphathwayo iinkcukacha malunga nobukhulu besixhobo esiqhelekileyo ziyakunikwa mhlawumbi.
Phakathi kwezizathu eziphambili zokumanyanisa iheader yoMsebenzisi-Agent kusetyenziso lwayo lokuchongwa kwabasebenzisi (ukuprintwa kweminwe), kunye nesenzo sokwenza i-header ngeziphequluli ezingaziwayo ukuqinisekisa ukusebenza kwendawo nganye (umzekelo, iVivaldi yi. inyanzeliswa ukuba iziveze kwiziza njengeChrome). Kwangelo xesha, i-Agent-Agent-fake kwi-browser yenqanaba lesibini ikwakhuthazwa nguGoogle uqobo, kuba ngokutsho kwe-Agent-Agent. ngena kwiinkonzo zakho. Ukumanyana kuya kusivumela ukuba silahle iimpawu eziphelelwe lixesha nezingenantsingiselo ezifana ne "Mozilla/5.0", "njengeGecko" kunye "njenge-KHTML" kumgca woMsebenzi woMsebenzi.
Kucetywa umatshini endaweni yoMsebenzisi-Arhente , oku kuthetha ukukhutshwa okukhethiweyo kwedatha malunga nomkhangeli othile kunye neeparameters zenkqubo (uguqulelo, iqonga, njl.) kuphela emva kwesicelo somncedisi kunye nokunika abasebenzisi ithuba lokubonelela ngolwazi olunjalo kubanikazi besayithi. Xa usebenzisa iingcebiso zoMxumi we-Agent-Agent, isichongi asihanjiswa ngokungagqibekanga ngaphandle kwesicelo esicacileyo, esenza ukuba uchongo olwenziwayo lungenzeki (ngokungagqibekanga, kuphela igama lomkhangeli libonisiwe).
Ngokumalunga nokuchongwa okusebenzayo, ulwazi olongezelelweyo olubuyisiweyo kwimpendulo yesicelo luxhomekeke kwizicwangciso zebrawuza (umzekelo, umsebenzisi unokwala ukuhambisa idatha konke konke), kwaye iimpawu ngokwazo zigqithisekile zigubungela inani elifanayo lolwazi njenge-Agent-Agent. umtya okwangoku. Isixa sedatha egqithiselweyo sixhomekeke kwimida , omisela umda kwixabiso ledatha enikeziweyo enokuthi isetyenziswe ukuchongwa - ukuba ukukhutshwa kolunye ulwazi kunokukhokelela ekwaphulwa kokungaziwa, ngoko ukufikelela ngakumbi kwii-API ezithile kuvaliwe. Itekhnoloji iphuhla ngaphakathi kwesakhelo senyathelo elinikezelwe ngaphambili , ejolise ekufezekiseni ulungelelwaniso phakathi kwesidingo sabasebenzisi ukugcina ubumfihlo kunye nomnqweno wothungelwano lwentengiso kunye neesayithi zokulandelela ukhetho lwabatyeleli.
