Tvrtka Google upozorila je na prekid podr\u0161ke za tehnologiju Server Push u izdanju Chrome 106, zakazanom za 27. rujna. Promjene \u0107e tako\u0111er utjecati na druge preglednike temeljene na Chromium kodnoj bazi. Tehnologija Server Push definirana je u standardima HTTP\/2 i HTTP\/3, a omogu\u0107ava serveru slanje resursa klijentu, ne \u010dekaju\u0107i njihov izri\u010dit zahtjev. Pretpostavlja se da server na ovaj na\u010din mo\u017ee ubrzati u\u010ditavanje stranice, tako da potrebni datoteke za iscrtavanje stranice, kao \u0161to su CSS, skripte i slike, budu ve\u0107 prenesene na klijentovu stranu do trenutka njihovog zahtjeva. <\/p>\n

Kao razlog za prekid podr\u0161ke navodi se prekompliciranje implementacije tehnologije uz postojanje jednostavnijih i jednako u\u010dinkovitih alternativa, poput oznake , na temelju koje preglednik mo\u017ee zatra\u017eiti resurs bez \u010dekanja na njegovo kori\u0161tenje na stranici. S jedne strane, preload u usporedbi s Server Push dovodi do dodatne izmjene paketa (RTT), no s druge strane omogu\u0107uje izbjegavanje slanja resursa koji su ve\u0107 u preglednikovom predmemoriji. Op\u0107enito, razlike u ka\u0161njenju pri kori\u0161tenju Server Push i preload-a ozna\u010dene su kao neznatne. <\/p>\n

Za iniciranje prethodnog u\u010ditavanja na strani poslu\u017eitelja<\/a> preporu\u010duje se kori\u0161tenje HTTP-odgovora 103, koji omogu\u0107uje obavje\u0161tavanje klijenta o sadr\u017eaju nekih HTTP-zaglavlja odmah nakon zahtjeva, ne \u010dekaju\u0107i da server dovr\u0161i sve povezane operacije i po\u010dne slati sadr\u017eaj. Na sli\u010dan na\u010din mogu se dati savjeti o povezanim elementima stranice koji se mogu prethodno u\u010ditati (na primjer, mogu biti navedene poveznice na kori\u0161tene CSS i JavaScript na stranici). Dobiv\u0161i informacije o takvim resursima, preglednik mo\u017ee zapo\u010deti njihovo u\u010ditavanje ne \u010dekaju\u0107i zavr\u0161etak slanja glavne stranice, \u0161to mo\u017ee skratiti ukupno vrijeme obrade zahtjeva. <\/p>\n

Osim optimizacije u\u010ditavanja resursa, mehanizam Server Push<\/a> tako\u0111er se mogao koristiti za prijenos podataka od poslu\u017eitelja do klijenta, no za te svrhe konzorcij W3C razvija protokol WebTransport. Kanali u WebTransportu organiziraju se iznad HTTP\/3 koriste\u0107i protokol QUIC kao transport. WebTransport nudi pro\u0161irene mogu\u0107nosti, kao \u0161to su organizacija prijenosa u vi\u0161e tokova, jednostrani tokovi, dostava bez obzira na redoslijed slanja paketa (out-of-order), pouzdani i nepouzdani na\u010dini dostave. <\/p>\n

Prema statistikama Googlea, tehnologija Server Push nije se dovoljno ra\u0161irila. Iako Server Push postoji u specifikaciji HTTP\/3, u praksi mnogi poslu\u017eiteljski i klijentski softverski proizvodi, uklju\u010duju\u0107i preglednik Chrome, izvorno ga nisu implementirali. U 2021. godini oko 1.25% web stranica koje rade na HTTP\/2 koristile su Server Push. Ove godine taj postotak smanjen je na 0.7%.
