Google har advaret om, at st\u00f8tte for Server Push-teknologien vil blive afbrudt i Chrome-version 106, planlagt til den 27. september. \u00c6ndringerne vil ogs\u00e5 p\u00e5virke andre browsere, der er baseret p\u00e5 Chromium-kodebasen. Server Push-teknologien er defineret i standarderne HTTP\/2 og HTTP\/3 og g\u00f8r det muligt for serveren at sende ressourcer til klienten uden at vente p\u00e5 deres eksplicitte foresp\u00f8rgsel. Det antages, at serveren p\u00e5 denne m\u00e5de kan fremskynde indl\u00e6sningen af siden, da de n\u00f8dvendige filer til rendering som CSS, scripts og billeder allerede vil v\u00e6re sendt til klientens side, n\u00e5r de bliver anmodet om. <\/p>\n

Som \u00e5rsag til oph\u00f8r af support n\u00e6vnes, at teknologien er blevet for kompliceret at implementere, n\u00e5r der findes enklere og lige s\u00e5 effektive alternativer, s\u00e5som tagget , hvilket g\u00f8r det muligt for browseren at anmode om ressourcen uden at vente p\u00e5 dens brug p\u00e5 siden. P\u00e5 den ene side f\u00f8rer preload, sammenlignet med Server Push, til un\u00f8dvendig pakkeudveksling (RTT), men p\u00e5 den anden side g\u00f8r det muligt at undg\u00e5 sending af ressourcer, der allerede er i browserens cache. Generelt er forskellene i forsinkelser ved brug af Server Push og preload blevet vurderet som ubetydelige. <\/p>\n

For at initiere forudindl\u00e6sning p\u00e5 klientens side server<\/a> foresl\u00e5s det at bruge HTTP-responskoden 103, som g\u00f8r det muligt at informere klienten om indholdet af nogle HTTP-headere straks efter foresp\u00f8rgslen, uden at vente p\u00e5, at serveren udf\u00f8rer alle operationer relateret til foresp\u00f8rgslen og begynder at levere indholdet. Lignende kan der gives hints om relaterede elementer til den leverede side, som kan indl\u00e6ses p\u00e5 forh\u00e5nd (for eksempel kan der gives links til de benyttede CSS- og JavaScript-filer p\u00e5 siden). Ved at modtage information om s\u00e5danne ressourcer kan browseren p\u00e5begynde indl\u00e6sningen, uden at vente p\u00e5, at den prim\u00e6re side er fuldt leveret, hvilket reducerer den samlede behandlingstid for foresp\u00f8rgslen. <\/p>\n

Udover optimering af ressourceindl\u00e6sning er mekanismen Server Push<\/a> kunne ogs\u00e5 anvendes til datastreaming fra serveren til klienten, men til disse form\u00e5l udvikler W3C-konsortiet protokollen WebTransport. Kommunikationskanalen i WebTransport oprettes over HTTP\/3 ved hj\u00e6lp af protokollen QUIC som transport. WebTransport tilbyder avancerede muligheder som multistreaming, ensretter str\u00f8mme, levering uden hensyntagen til pakkeordre (out-of-order) og b\u00e5de p\u00e5lidelige og up\u00e5lidelige leveringsmetoder. <\/p>\n

If\u00f8lge Google-statistik har teknologien Server Push ikke f\u00e5et den \u00f8nskede udbredelse. Selvom Server Push er til stede i specifikationen for HTTP\/3, har mange server- og klientprogrammer, herunder Chrome-browseren, ikke implementeret den fra starten. I 2021 brugte omkring 1,25% af webstederne, der k\u00f8rte p\u00e5 HTTP\/2, Server Push. I \u00e5r er denne procentdel faldet til 0,7%.
