Akhrinta Upload-ka qaybo kala duwan ma u baahan Chunked HTTP
Kala saar akhrinta xaddidan ee barnaamijka iyo qaabaynta fariinta HTTP/1.1 marka upload-ku si ka duwan u dhaqmo marka loo marayo forward proxy.
Maya. Macmiilku wuxuu akhrin karaa fayl weyn isagoo isticmaalaya buffers yaryar, kaddibna wuxuu ku diri karaa Content-Length la yaqaan. Akhrinta xaddidan waxay xakameysaa isticmaalka xusuusta; qaabaynta HTTP-na waxay u sheegtaa qaataha halka jidhka codsigu ku dhammaado.
Fayl xasilloon oo dhererkiisa byte-ka ah uu maktabadda HTTP taqaan wuu ka duwan yahay generator soo saara xaddi aan la garanayn oo xog ah. Isticmaal interface-ka jidhka ee maktabaddu taageerto labada isha. Uma baahnid inaad faylka oo dhan isugu keento hal string si aad u bixiso dherer.
HTTP/1.1, baadh qaabaynta dhab ahaan la diray: Content-Length ama chunked transfer coding sida uu qorayo xeerka borotokoolka. Chunked coding waxay ku daraysaa calaamado cabbir dibadda nuxurka faylka. Ha isku darin goobo qaabayn is burinaya, hana qiyaasin dherer si aad proxy uga dhaadhiciso inuu aqbalo upload-ka.
Haddii upload lagu maray proxy uu fashilmo, diiwaangeli nooca HTTP, isha jidhka iyo diidmadii ugu horreysay. Jawaabta 411 waxay soo jeedinaysaa baaritaan ka duwan midka xiriirka badhka jidhka ka go'ay. Haddii dib-u-celinta xaqiijinta ay fashilmaan, hubi in jidhka upload-ka dib loo ciyaari karo. Beddelka cabbirka buffer-ka akhrinta ee barnaamijku waxaa laga yaabaa inuu qaabaynta codsiga sida ay tahay uga tago.
Wadadu waa muhiim u tahay observation-kaas. Gudbinta plaintext waxay qaabaynta HTTP ee upload-ka u bandhigtaa proxy-ga; HTTPS caadi ah oo end-to-end ah waxay ku dhex dhigtaa tunnel. HTTP/2 waxay isticmaashaa qaabaynta u gaar ah. Sidaas darteed xaddidnaanta Squid ee taariikhiga ah waxay sharraxaan fashilmo hore oo gaar ah, ma aha xeer sheegaya in proxy kasta oo hadda jira uu diido upload-ka streamed.
