Compania Google a avertizat cu privire la suspendarea suportului pentru tehnologia Server Push \u00een actualizarea Chrome 106, programat\u0103 pentru 27 septembrie. Modific\u0103rile vor afecta \u0219i alte browsere bazate pe codul surs\u0103 Chromium. Tehnologia Server Push este definit\u0103 \u00een standardele HTTP\/2 \u0219i HTTP\/3 \u0219i permite serverului s\u0103 trimit\u0103 resurse c\u0103tre client f\u0103r\u0103 a a\u0219tepta o solicitare explicit\u0103. Se consider\u0103 c\u0103 astfel serverul poate accelera \u00eenc\u0103rcarea paginii, deoarece fi\u0219ierele CSS, scripturile \u0219i imaginile necesare pentru redarea paginii vor fi deja transferate c\u0103tre client la momentul solicit\u0103rii. <\/p>\n

Ca motiv al suspend\u0103rii suportului este men\u021bionat\u0103 complicarea excesiv\u0103 a implement\u0103rii tehnologiei \u00een prezen\u021ba unor alternative mai simple \u0219i la fel de eficiente, cum ar fi eticheta , pe baza c\u0103reia browserul poate solicita un resurs f\u0103r\u0103 a a\u0219tepta utilizarea acestuia pe pagin\u0103. Pe de o parte, preload, \u00een compara\u021bie cu Server Push, conduce la un schimb excesiv de pachete (RTT), dar, pe de alt\u0103 parte, permite evitarea trimiterii resurselor deja prezente \u00een cache-ul browserului. \u00cen general, diferen\u021bele de laten\u021b\u0103 \u00eentre utilizarea Server Push \u0219i preload au fost observate ca fiind nesemnificative. <\/p>\n

Pentru ini\u021bierea \u00eenc\u0103rc\u0103rii proactive pe partea server<\/a> se propune utilizarea codului de r\u0103spuns HTTP 103, care permite informarea clientului despre con\u021binutul unor antete HTTP imediat dup\u0103 solicitare, f\u0103r\u0103 a a\u0219tepta ca serverul s\u0103 finalizeze toate opera\u021biunile asociate cu solicitarea \u0219i s\u0103 \u00eenceap\u0103 livrarea con\u021binutului. \u00cen acest mod pot fi comunicate sugestii despre elementele legate de pagina livrat\u0103, care pot fi \u00eenc\u0103rcate \u00een prealabil (de exemplu, linkuri c\u0103tre CSS \u0219i JavaScript utilizate pe pagin\u0103). Ob\u021bin\u00e2nd informa\u021bii despre astfel de resurse, browserul poate \u00eencepe \u00eenc\u0103rcarea lor f\u0103r\u0103 a a\u0219tepta finalizarea livr\u0103rii paginii principale, ceea ce permite reducerea timpului total de procesare a solicit\u0103rii. <\/p>\n

Pe l\u00e2ng\u0103 optimizarea \u00eenc\u0103rc\u0103rii resurselor, mecanismul Server Push<\/a> poate fi folosit \u0219i pentru transmiterea de date de la server la client, dar pentru aceste scopuri, consor\u021biul W3C dezvolt\u0103 protocolul WebTransport. Canalul de comunica\u021bie \u00een WebTransport este organizat deasupra HTTP\/3 folosind protocolul QUIC ca transport. WebTransport ofer\u0103 func\u021bionalit\u0103\u021bi avansate, cum ar fi organizarea transmisiilor \u00een mai multe fluxuri, fluxuri unidirec\u021bionale, livrarea f\u0103r\u0103 respectarea ordinii de trimitere a pachetelor (out-of-order), moduri de livrare fiabile \u0219i nesigure. <\/p>\n

Conform statisticilor Google, tehnologia Server Push nu a avut o r\u0103sp\u00e2ndire semnificativ\u0103. De\u0219i Server Push este inclus \u00een specifica\u021bia HTTP\/3, \u00een practic\u0103, multe produse software de server \u0219i client, inclusiv browserul Chrome, nu l-au implementat ini\u021bial. \u00cen 2021, aproximativ 1.25% din site-urile care func\u021bionau pe HTTP\/2 utilizau Server Push. \u00cen acest an, aceast\u0103 propor\u021bie a sc\u0103zut la 0.7%.
