Per avviare il caricamento anticipato dal lato server<\/a> si consiglia di utilizzare il codice di risposta HTTP 103, che consente di informare il client sul contenuto di alcuni intestazioni HTTP subito dopo la richiesta, senza attendere che il server esegua tutte le operazioni associate alla richiesta e inizi a fornire il contenuto. In questo modo \u00e8 possibile comunicare suggerimenti sugli elementi correlati alla pagina restituita, che possono essere caricati in anticipo (ad esempio, possono essere forniti i link ai CSS e JavaScript utilizzati nella pagina). Ricevendo informazioni su tali risorse, il browser pu\u00f2 iniziare a caricarle senza attendere il completamento della fornitura della pagina principale, riducendo cos\u00ec il tempo totale di elaborazione della richiesta. <\/p>\n

Oltre all'ottimizzazione del caricamento delle risorse, il meccanismo Server Push<\/a> poteva anche essere utilizzato per lo streaming di dati dal server al cliente, ma per questi scopi il consorzio W3C sta sviluppando il protocollo WebTransport. Il canale di comunicazione in WebTransport \u00e8 organizzato sopra HTTP\/3 utilizzando come trasporto il protocollo QUIC. WebTransport offre funzionalit\u00e0 avanzate come la gestione della trasmissione su pi\u00f9 flussi, flussi unidirezionali, consegna senza considerazione dell'ordine di invio dei pacchetti (out-of-order), modalit\u00e0 di consegna affidabili e non affidabili. <\/p>\n

Secondo le statistiche di Google, la tecnologia Server Push non ha avuto una diffusione adeguata. Anche se Server Push \u00e8 presente nella specifica di HTTP\/3, nella pratica molti prodotti software server e client, incluso il browser Chrome, inizialmente non lo hanno implementato. Nel 2021, circa l'1,25% dei siti che operavano su HTTP\/2 utilizzavano Server Push. Quest'anno, questa percentuale \u00e8 scesa allo 0,7%.
