Ukuhlaziya ama-Connection Header e-HTTP njengamathokheni ahlukaniswe ngokhefana
Hlaziya zonke izinketho ze-Connection ngaphandle kokubheka uhlamvu olukhulu noma oluncane lapho i-forward proxy ihlangana ne-keep-alive ne-Upgrade kusigaba esisodwa se-HTTP/1.1.
La mavelu awazona izindlela zokubhala eziqhudelanayo zendlela eyodwa:
Connection: Upgrade
Connection: keep-alive, UpgradeEyesibili ibala izinketho ezimbili zokuxhumana. I-HTTP ichaza i-Connection njengohlu oluhlukaniswe ngokhefana, futhi amagama ezinketho awabheki uhlamvu olukhulu noma oluncane. Ikhodi eqhathanisa lonke inani nomugqa oqondile we-Upgrade yehluleka ukuthola uhlu olufanele oluqukethe leyo nketho.
Ekudluliseleni okuvamile, isixhumanisi se-HTTP sihlaziya insimu engenayo, sisuse izinsimu eziqanjwe yizinketho zaso, bese sisusa i-Connection uqobo noma siyishintshe ngezinketho zaso zokuphatha zokuxhumana okulandelayo.
Ukususa kuphela insimu ye-Keep-Alive ebhalwe ngokuqinile akwanele. Umlayezo ungase uqambe enye insimu eqondene nokuxhumana ohlwini, futhi leyo nsimu akumele ingene ekudluliseleni okuvamile.
Ukusekela ukuthuthukiswa kwephrothokholi kudinga ukuphatha ngamabomu ukuxhumana okubili nephrothokholi entsha. Ukukopisha ngobumpumputhe ama-Upgrade header angenayo akusikho ukuqaliswa kwalokho kudluliswa.
Lapho isiphequluli esisodwa sisebenza futhi esinye sehluleka, qhathanisa amanani angempela ensimu ezinhlangothini zombili zesixhumanisi. Umehluko phakathi kwethokheni eyodwa nohlu lwamathokheni amabili ungadalula iphutha lomhlaziyi ngaphandle kokudinga ukuthi isiphequluli silingise ukufometha okuqondile kwesinye isiphequluli.
Lokhu kumayelana nemilayezo ye-HTTP ehlaziywa yi-proxy. Ithubhu elivamile le-HTTPS CONNECT alidaluli insimu ye-Connection yewebhusayithi ebethelwe kuleyo proxy.
