Lapho ifayela elilandiwe liqala ngomugqa wesimo we-HTTP
Gcina ukufakwa kohlaka kokuphendula kwe-HTTP ngaphandle kwefayela elilandiwe esikhundleni sokukopisha yonke ibhayithi etholakala kusokhethi ye-proxy kufayela lokuphuma.
Uma i-PDF noma ispredishithi okucatshangwa ukuthi iyona iqala nge-HTTP/1.1 200 OK, isilandi sigeine impendulo eluhlaza esikhundleni sefayela. Le mpendulo yomdwebo inamabayithi amane kuphela okuqukethwe:
HTTP/1.1 200 OK
Transfer-Encoding: chunked
4
DATA
0
Ifayela liyi-DATA. Umugqa wesimo, izihloko, uphawu losayizi kanye nesakhiwo sokuphetha kungokwe-HTTP. Ukususa inani elingaguquki lamabayithi akuphephile ngoba ubude bezihloko buyehluka. Ukukopisha konke ngemva komugqa wokuqala ongenalutho kusashiya uhlaka lwezingxenye, futhi izimpendulo zolwazi zingafika ngaphambi kwempendulo yokugcina.
Ukolanda okuvamile, shintsha ukukopisha kusokhethi eluhlaza kuya kufayela ngesixhumi somzimba wempendulo sekhliyente ye-HTTP. Lungiselela i-proxy yayo, qinisekisa isimo sokugcina bese usakaza umzimba kokokukhipha kwesikhashana. Ikhliyente ibhekana nokufakwa kohlaka komlayezo: imizimba ekhawulelwe ngobude, ngezingxenye (chunked) futhi ekhawulelwe ukuxhumana idinga ukuhlaziywa okuhlukile.
Ukubhalwa kwekhodi kokuqukethwe kungolunye ungqimba. Nquma ukuthi udinga amabayithi efayela akhodiwe noma okuqukethwe okuluhlaza okuceliwe ngokusobala, usebenzisa ukuziphatha okubhaliwe kwekhliyente. Amabayithi acindezelwe awakona ukonakala kwe-proxy ngokuzenzakalela.
Uma uhlelo kufanele lugcine ikhodi yezinga lesokhethi, yilo olunomthwalo wemfanelo wazo zonke lezo zinhlelo zokuhlaziya kanye nokuphatha ukufunda nokubhala. Bhala kuphela inani lamabayithi okufunda akubuyisele ngempela, hhayi umthamo webhafa, futhi uphathe ukubhala okuyingxenye. Ngaphandle kwalokho okuqukethwe kwebhafa okuphelelwe yisikhathi kungonakalisa ngisho umzimba okhishwe ngendlela efanele.
I-HTTPS idinga okungaphezu kokususa impendulo ye-CONNECT: ngemva kokusungulwa okuphumelelayo kwethuneli, sungula i-TLS yendawo ekuyiwa kuyo bese uhlaziya impendulo ye-HTTP yangaphakathi. Amabayithi abethelwe ngemva kwezihloko ze-proxy akuwona ifayela elilande-kayo.
Shiya okukhiphayo okuhlulekile noma okungaphelele ngaphansi kwegama lesikhashana. Kushicilele kuphela ngemva kokuba ukudluliswa kanye nokuhlolwa kwefayela kuphumelele; ifayela elingenalutho alibonisi ukulanda okuphelele.
