Google on teatanud, et Chrome 106 versioonis, mis toimub 27. septembril, l\u00f5petatakse Server Push tehnoloogia toetus. Muudatused puudutavad ka teisi brausereid, mis p\u00f5hinevad Chromiumi koodibaasil. Server Push tehnoloogia on m\u00e4\u00e4ratletud HTTP\/2 ja HTTP\/3 standardites ning v\u00f5imaldab serveril saata ressursse kliendile, ootamata nende selget taotlust. Eeldatakse, et see v\u00f5imaldab serveril lehe laadimist kiirendada, kuna vajalikud lehe renderdamiseks vajalikud CSS-failid, skriptid ja pildid on enne kliendi taotlust juba edastatud. <\/p>\n

Toetamiseks l\u00f5petamise p\u00f5hjuseks tuuakse v\u00e4lja tehnoloogia \u00fclem\u00e4\u00e4rane keerukus v\u00f5rreldes lihtsamate ja mitte v\u00e4hem t\u00f5husate alternatiividega, nagu m\u00e4rk, mille alusel saab brauser ressursi k\u00fcsida, ootamata selle kasutamist lehel. \u00dchelt poolt toob preload v\u00f5rreldes Server Push'iga kaasa liigse pakettide vahetuse (RTT), kuid teiselt poolt v\u00f5imaldab see v\u00e4ltida ressursside saatmist, mis on juba brauseri vahemikus. \u00dcldiselt on Server Push'i ja preload'i kasutamise viivituste erisused hinnatud kui ebaolulised. <\/p>\n

Eelneva laadimise algatamiseks serverile<\/a> soovitakse kasutada HTTP-respondendi koodi 103, mis v\u00f5imaldab kohe p\u00e4rast taotlust informeerida klienti teatud HTTP-pealkirjade sisust, ootamata serveri k\u00f5igi taotlusega seotud operatsioonide t\u00e4itmist ja sisu edastamist. Nii saab edastada vihjeid seotud elementide kohta, mille laadimist saab eelnevalt alustada (n\u00e4iteks saadetakse lingid lehe kasutatavale CSS-ile ja JavaScriptile). Saades teavet selliste ressursside kohta, saab brauser nende laadimist alustada enne p\u00f5hilehe edastamise l\u00f5petamist, mis l\u00fchendab taotluse koguaega. <\/p>\n

Lisaks ressursside laadimise optimeerimisele Server Push<\/a> v\u00f5is ka andmeid serverist kliendile voogedastamiseks rakenduda, kuid nende eesm\u00e4rkide saavutamiseks arendab W3C konsortsium WebTransport protokolli. WebTransporti suhtluskanal korraldatakse HTTP\/3 kohal, kasutades transpordina QUIC protokolli. WebTransport pakub selliseid t\u00e4iustatud v\u00f5imalusi nagu andmete edastamine mitme vooga, \u00fchesuunalised vood, pakettide j\u00e4rjekorra ignoreerimine (out-of-order) ning usaldusv\u00e4\u00e4rsed ja usaldamatud edastusre\u017eiimid. <\/p>\n

Google'i statistika kohaselt ei ole Server Push tehnoloogia laialdast levikut leidnud. Kuigi Server Push on HTTP\/3 spetsifikatsioonis, ei ole paljude serverite ja kliendi tarkvarade, sealhulgas Chrome'i brauseri, puhul selle rakendamine algselt toimunud. 2021. aastal kasutas umbes 1,25% HTTP\/2 kaudu t\u00f6\u00f6tavatest saitidest Server Pushi. Sel aastal on see n\u00e4itaja langenud 0,7%-ni.
