Ukwehluleka kwe-DNS ochungechungeni lwe-proxy ye-HTTP: yiliphi igxathu elixazulula igama?
Hlukanisa ukufinyelela ku-proxy yasendaweni, ukuxazulula umzali kanye nokuxazulula iwebhusayithi lapho uhlola i-forward proxy enochungechunge.
client → local forward proxy → HTTP parent → websiteQala ngegama elihlulekayo esikhundleni sokuthi yonke i-DNS ingeye-«proxy»:
| Igama elidingekayo | Igxathu okufanele lifinyelele kulo |
|---|---|
| Iphedi yokugcina ye-proxy yasendaweni | Iklayenti |
| Iphedi yokugcina yomzali we-HTTP | I-forward proxy yasendaweni |
| Iphedi yokugcina yewebhusayithi | Umzali lapho evula ukuxhumana kokugcina |
Lawu magxathu angasebenzisa izixazululi ezahlukene lapho amaphedi okugcina engamagama omphathi. Ku-HTTPS, i-forward proxy ingadlulisela umzali umphathi nembobo yendawo ye-CONNECT, oqala ukuxhumana kokugcina. Iklayenti lokuqala akudingeki lixazulule iwebhusayithi kuqala. Ukudluliselwa kwe-HTTP okuvamile nakho kudlulisela imininingwane yendawo phambili.
Lokhu akusiso isithembiso sokuthi umshini owodwa uphela ubuza igama ngalinye. Ukuhlolwa kwe-ACL, ukugcina emkhumbini, inqubomgomo kanye nemininingwane yokuqalisa kungabangela ukusesha okwengeziwe.
Hlola inqubomgomo yokubuyela emuva lapho umzali engekho. Uma ukufinyelela okuqondile kuvunyelwe, i-proxy yasendaweni ingaba igxathu elibheke ewebhusayithini, ngezinqumo zayo zesixazululi nekheli lomthombo. Ukumisa umzali kuphela akufakazeli ukuthi zonke izicelo ziwusebenzisile.
Lapho kwehluleka, khomba igama kanye nenqubo ezama ukulixazulula ngaphambi kokuhlela ifayela le-hosts. Ukuhlela ohlangothini lweklayenti akukwazi ukulungisa zonke izinqumo ezilandelayo. Umthombo womphakathi wokugcina ungowegxathu elivula ukuxhumana newebhusayithi; ukubuka lowo mthombo akufani nokukala ukuthi i-DNS yenzeke kuphi.
