Google teatas, et Chrome 106 v\u00e4ljaandes, mis on planeeritud 27. septembriks, l\u00f5petatakse Server Push tehnoloogia toetus. Muud Chromiumi koodibaasil p\u00f5hinevad brauserid saavad samuti sellega seotud muudatusi. Server Push tehnoloogia on m\u00e4\u00e4ratletud HTTP\/2 ja HTTP\/3 standardites ja v\u00f5imaldab serveril saata kliente ressursse, ootamata nende \u00fchtekuuluvate p\u00e4ringute esitamist. Eeldatakse, et see v\u00f5imaldab serveril kiirendada lehe laadimist, kuna CSS-failid, skriptid ja pildid, mis on lehe kuvamiseks vajalikud, on juba edastatud, kui klient need l\u00f5puks p\u00e4rib. <\/p>\n

Toetamiseks l\u00f5petamise p\u00f5hjuseks tuuakse v\u00e4lja tehnoloogia rakendamise liigne keerukus, olemasolevate lihtsamate ja mitte v\u00e4hem efektiivsete alternatiivide, nagu silt, olemasolu, mille alusel saab brauser ressursse k\u00fcsida, ilma et peaksite ootama nende kasutamist lehel. \u00dchelt poolt toob preload v\u00f5rreldes Server Pushiga kaasa liigset pakettide vahetust (RTT), kuid teiselt poolt v\u00f5imaldab v\u00e4ltida ressursside saatmist, mis on juba brauseri vaCaches. \u00dcldiselt on Server Pushi ja preloadi kasutamise viivituse erisused peetud ebaoluliseks. <\/p>\n

Eelneva laadimise algatamiseks on soovitatav kasutada HTTP vastuse koodi 103, mis v\u00f5imaldab kliendile edastada teavet m\u00f5nede HTTP-pealkirjade sisu kohta kohe p\u00e4rast p\u00e4rimist, ootamata serveri t\u00e4iustatud operatsioonide l\u00f5petamist ja sisu edastamise alustamist. Sel viisil saab edastada vihjeid seotud leheelementide kohta, mida saab eelnevalt laadida (n\u00e4iteks CSS ja JavaScript lingid, mida kasutatakse lehel). Saades teavet selliste ressursside kohta saab brauser alustada nende laadimist, ootamata peamise lehe edastamisprotsessi l\u00f5petamist, mis v\u00f5imaldab v\u00e4hendada kogu p\u00e4ringu t\u00f6\u00f6tlemise aega. serverilt<\/a> Lisaks ressursside laadimise optimeerimisele on Server Push mehhanism <\/p>\n

Server Push Server Push<\/a> seda saab kasutada andmete edastamiseks serverist kliendile, kuid selleks arendab W3C organisatsioon protokolli WebTransport. WebTransporti sidekanal on \u00fcles ehitatud HTTP\/3 peale, kasutades transpordiks protokolli QUIC. WebTransport pakub selliseid arenenud funktsioone nagu mitme voolu edastamise korraldamine, \u00fchesuunalised voolud, paketide edastamine j\u00e4rjekorra j\u00e4rgi (out-of-order) sek\u00e4 usaldusv\u00e4\u00e4rsed ja usaldamatud edastamisre\u017eiimid. <\/p>\n

Google'i statistika kohaselt ei ole Server Push tehnoloogia laialdaselt levinud. Kuigi Server Push on olemas HTTP\/3 spetsifikatsioonis, ei rakendanud paljud serveri- ja kliendiprogrammid, sealhulgas Chrome'i brauser, seda algselt. 2021. aastal kasutas umbes 1,25% HTTP\/2 kaudu t\u00f6\u00f6tavatest saitidest Server Pushi. Selle aasta jooksul on see n\u00e4itaja langenud 0,7% -ni.
