Ukufunda Ukulayishwa Ngezingxenye Akudingi I-Chunked HTTP
Hlukanisa ukufunda okulinganiselwe kohlelo kusuka ekwakhiweni komlayezo we-HTTP/1.1 lapho ukulayishwa kuziphatha ngendlela ehlukile nge-forward proxy.
Cha. Iklayenti lingafunda ifayela elikhulu kumabhafara amancane bese lilithumela nge-Content-Length eyaziwayo. Ukufunda okulinganiselwe kulawula ukusetshenziswa kwenkumbulo; ukwakhiwa kwe-HTTP kutshela umamukeli ukuthi umzimba wesicelo uphela kuphi.
Ifayela elizinzile ubude balo bamabhayithi olwaziwe yilabhulali ye-HTTP lehlukile kusijenerethi esikhiqiza inani elingaziwa ledatha. Sebenzisa isixhumi somzimba esisekelwa yilabhulali kunoma yimuphi umthombo. Awudingi ukuhlanganisa lonke ifayela libe yuchungechunge ukuze nje unikeze ubude.
Kwe-HTTP/1.1, hlola ukwakhiwa okuthunyelwe ngempela: Content-Length noma i-chunked transfer coding ngaphansi kwemithetho yephrothokholi. Ukubhala nge-chunked kwengeza izimpawu zosayizi ngaphandle kokuqukethwe kwefayela. Ungahlanganisi izinkambu zokwakha eziphikisanayo futhi ungaqageli ubude ukuze ukholise i-proxy ukuthi yamukele ukulayishwa.
Uma ukulayishwa nge-proxy kwehluleka, rekhoda inguqulo ye-HTTP, umthombo womzimba kanye nokwenqatshwa kokuqala. Impendulo engu-411 iphakamisa uphenyo oluhlukile kunokuxhumana okuvalwa phakathi nomzimba. Uma izilingo zokuqinisekisa zingaphumeleli esikhundleni salokho, hlola ukuthi umzimba wokulayishwa ungadlalwa yini futhi. Ukushintsha usayizi webhafara lokufunda lohlelo kungase kushiye ukwakhiwa kwesicelo kunjalo.
Indlela ibalulekile kulokho kuqaphela. Ukudlulisa ngombhalo osobala kuveza ukwakhiwa kwe-HTTP kokulayishwa ku-proxy; i-HTTPS ejwayelekile yokuphela-kuya-ekupheleni kuyifaka ngaphakathi komhubhe. I-HTTP/2 isebenzisa ukwakhiwa kwayo. Ngakho imikhawulo yomlando ye-Squid ichaza ukwehluleka okuthile kwakudala, hhayi umthetho wokuthi yonke i-proxy yamanje yenqaba ukulayishwa okusakazwayo.
