Okusha inqubo esetshenzisiwe ukukhomba isibonelo sesiphequluli. Indlela kusekelwe kuzici zokucubungula isithombe zeFavicon ngosizo lapho isayithi linquma khona izithonjana eziboniswa kumabhukhimakhi, kumathebhu nakwezinye izinto zesixhumi esibonakalayo sesiphequluli.
Iziphequluli zigcina izithombe ze-Favicon kunqolobane ehlukile, engadluli nezinye izinqolobane, ijwayelekile kuzo zonke izindlela zokusebenza, futhi ayisuswa ngabahlanzeli abajwayelekile benqolobane nokuphequlula.
Lo msebenzi ivumela ukusebenzisa isikhombi noma ngabe usebenza kumodi ye-incognito futhi kwenza kube nzima ukususa. Ukufakazela ubuqiniso besebenzisa indlela ehlongozwayo nakho akuphazamiseki ukusetshenziswa kwama-VPNs nama-plug-block okuvimbela izikhangiso.
Indlela yokuhlonza isuselwa eqinisweni lokuthi ohlangothini lweseva kungenzeka ukunquma ukuthi ngabe umsebenzisi wake walivula yini ikhasi ngaphambilini ngokuhlaziya imininingwane emayelana nomthwalo we-Favicon uma isiphequluli singazange sicele isithombe se-Favicon esichazwe kumingcele yekhasi , bese ikhasi lilayishwa ngaphambili futhi isithombe sikhonjiswa kusuka kunqolobane.
Njengoba lIziphequluli zikuvumela ukuthi ulungiselele i-Favicon yakho ekhasini ngalinye, imininingwane ewusizo ingafakwa ngekhodi ngokudlulisa okulandelanayo kusuka kumsebenzisi kuya kumakhasi amaningi ahlukile.
Ukuqondiswa kabusha okuningi kuketanga, izikhombi ezingaphezulu zinganqunywa (inani lezikhombi linqunywa ifomula 2 ^ N, lapho uN kuyinombolo yokuqondisa kabusha). Isibonelo, abasebenzisi be-4 bangabhekana nokuqondisa kabusha okubili, i-3-8, 4-16, 10-1024, 24-16 yezigidi, i-32-4 billion.
Okubi ngale ndlela ukubambezeleka okude- Ukuphakama ngokunemba, kuthatha isikhathi eside ukuqondisa kabusha ukuvula ikhasi.
Ukuqondisa kabusha okungama-32 kukhiqiza okokuhlonza kwabo bonke abasebenzisi be-Intanethi, kepha kubangela ukubambezeleka cishe kwemizuzwana emithathu. Kokuhlonza okuyisigidi, ukubambezeleka cishe kuyimizuzwana eyodwa nohhafu.
Le ndlela ifaka phakathi ukusebenza ngezindlela ezimbili: ukubhala nokufunda:
- Imodi yokubhala yakha futhi igcine okokuhlonza umsebenzisi oqale wafinyelela isiza.
- Imodi yokufunda ifunda isikhombi esasigcinwe ngaphambilini.
Ukukhethwa kwemodi kuya ngesicelo sefayela le-Favicon sekhasi eliyinhloko lesayithi: uma isithombe siceliwe, idatha ayilondoloziwe futhi kungacatshangwa ukuthi umsebenzisi akaze afinyelele kusayithi ngaphambili noma okuqukethwe kulondolozwe iphelelwe yisikhathi. Ngokusho kwabaphenyi, ngokucacisa iheda ye-HTTP Cache-Control, kungenzeka ukufeza i-Favicon kunqolobane kuze kube unyaka owodwa.
Kumodi yokufunda, lapho uvula isayithi, umsebenzisi uboshelwe emakhasini achazwe ngaphambilini ngeFavicons yakhe futhi Amaseva we-HTTP adlulisa amaFavicons aceliwe kuseva futhi lokho kukhonjiswa ngaphandle kokufinyelela kuseva kusuka kunqolobane. Ukuba khona kwesicelo kufakwe ikhodi njengo- "0" nokungabikho njengo- "1". Ukuze okokuhlonza kugcinwe kwizingcingo ezizayo, kukhonjiswa ikhodi yephutha engu-404 ngokuphendula izicelo ze-Favicon, okusho ukuthi, ngesikhathi esizayo lapho uvula isayithi, isiphequluli sizozama ukulayisha la ma-favicon futhi.
Kumodi yokubhala, ku-loop eqondisa kabusha yamakhasi wokufaka ikhodi "1", kuyabuyiselwa impendulo eyiyo yeFavicon, efakwe kunqolobane yesiphequluli (lapho umjikelezo uphindwa, idatha ye-Favicon izobuyiselwa kusuka kunqolobane, ngaphandle kokufinyelela kuseva), kanye namakhasi afaka ikhodi "0" - ikhodi yephutha 404 (uma uphinda umjikelezo oqondisa kabusha, idatha yekhasi izocelwa futhi).
Le ndlela isebenza ku-Chrome, Safari, Edge nakancane kuFirefox. KuFirefox yeLinux, ukusetshenziswa kwamaFavicons njengamaSupercookies kuthikamezwa yisici esivimbela isiphequluli ekulondolozeni isikhangiso iFavicon.
Kuyathakazelisa ukuthi ababhali bendlela yokufakazela ubuqiniso bazise abathuthukisi beFirefox ngalesi sici esikhathini esingangonyaka esedlule, bebona ukuthi kube nephutha kunqolobane, kodwa bengasho lutho ngomsebenzi wabo nokuthi ukulungisa iphutha kungaholela ekutholakaleni komsebenzisi.
