Google har meddelat att de kommer att avbryta st\u00f6det f\u00f6r Server Push-tekniken i Chrome-version 106, planerat till den 27 september. \u00c4ndringarna kommer ocks\u00e5 att p\u00e5verka andra webbl\u00e4sare som bygger p\u00e5 Chromium-kodbasen. Server Push-teknologin definieras i HTTP\/2- och HTTP\/3-standarderna och m\u00f6jligg\u00f6r f\u00f6r servern att skicka resurser till klienten utan att v\u00e4nta p\u00e5 ett uttryckligt beg\u00e4ran. Det f\u00f6rv\u00e4ntas att detta kan p\u00e5skynda sidladdningen, eftersom n\u00f6dv\u00e4ndiga filer som CSS, skript och bilder kommer att ha \u00f6verf\u00f6rts innan klienten beg\u00e4r dem. <\/p>\n

Som anledning till att st\u00f6det upph\u00f6r n\u00e4mns den \u00f6verdrivna komplexiteten i implementeringen av teknologin, trots att det finns enklare och minst lika effektiva alternativ, s\u00e5som taggen , som g\u00f6r att webbl\u00e4saren kan beg\u00e4ra resurser utan att v\u00e4nta p\u00e5 att de ska anv\u00e4ndas p\u00e5 sidan. \u00c5 ena sidan leder preload i j\u00e4mf\u00f6relse med Server Push till on\u00f6dig paketutbyte (RTT), men \u00e5 andra sidan g\u00f6r det att man kan undvika att skicka resurser som redan finns i webbl\u00e4sarens cache. Sammanfattningsvis har skillnaderna i f\u00f6rdr\u00f6jningar mellan Server Push och preload noterats som obetydliga. <\/p>\n

F\u00f6r att initiera f\u00f6rhandsladdning p\u00e5 klientsidan servern<\/a> f\u00f6resl\u00e5s att anv\u00e4nda HTTP-svarskoden 103, som g\u00f6r det m\u00f6jligt att informera klienten om inneh\u00e5llet i vissa HTTP-huvuden omedelbart efter f\u00f6rfr\u00e5gan, utan att v\u00e4nta p\u00e5 att servern ska utf\u00f6ra alla relaterade operationer och b\u00f6rja leverera inneh\u00e5llet. P\u00e5 detta s\u00e4tt kan man ge ledtr\u00e5dar om relaterade element kopplade till den levererade sidan som kan laddas i f\u00f6rv\u00e4g (till exempel kan l\u00e4nkar till anv\u00e4nda CSS- och JavaScript-filer ges). N\u00e4r webbl\u00e4saren f\u00e5r information om s\u00e5dana resurser kan den b\u00f6rja ladda dem utan att v\u00e4nta p\u00e5 att huvud sidan ska skickas, vilket g\u00f6r att den totala f\u00f6rfr\u00e5gningstiden kan kortas. <\/p>\n

F\u00f6rutom optimering av resursladdning Server Push<\/a> kunde ocks\u00e5 anv\u00e4ndas f\u00f6r datastreaming fr\u00e5n servern till klienten, men f\u00f6r dessa \u00e4ndam\u00e5l utvecklar W3C-konsortiet protokollet WebTransport. Kommunikationskanalen i WebTransport organiseras ovanp\u00e5 HTTP\/3 med anv\u00e4ndning av QUIC-protokollet som transport. WebTransport erbjuder avancerade funktioner s\u00e5som flertr\u00e5dad \u00f6verf\u00f6ring, enkelriktade str\u00f6mmar, leverans utan ordning i paket (out-of-order), samt tillf\u00f6rlitliga och otillf\u00f6rlitliga leveransl\u00e4gen. <\/p>\n

Enligt Google-statistik har teknologin Server Push inte f\u00e5tt n\u00e5got st\u00f6rre genomslag. Trots att Server Push finns i specifikationen f\u00f6r HTTP\/3 har m\u00e5nga server- och klientprogram, inklusive webbl\u00e4saren Chrome, initialt inte implementerat den. \u00c5r 2021 anv\u00e4nde cirka 1,25 % av webbplatserna som k\u00f6rde HTTP\/2 Server Push. I \u00e5r har den siffran sjunkit till 0,7 %.
