La empresa Google ha advertido sobre la desactivaci\u00f3n del soporte para la tecnolog\u00eda Server Push en la versi\u00f3n de Chrome 106, programada para el 27 de septiembre. Los cambios tambi\u00e9n afectar\u00e1n a otros navegadores basados en la base de c\u00f3digo Chromium. La tecnolog\u00eda Server Push se define en los est\u00e1ndares HTTP\/2 y HTTP\/3, y permite al servidor enviar recursos al cliente sin esperar a que se soliciten expl\u00edcitamente. Se supone que, de esta manera, el servidor puede acelerar la carga de la p\u00e1gina, ya que los archivos CSS, scripts e im\u00e1genes necesarios para renderizar la p\u00e1gina estar\u00e1n ya enviados al momento de la solicitud del cliente. <\/p>\n

La raz\u00f3n mencionada para la interrupci\u00f3n del soporte es la complejidad excesiva en la implementaci\u00f3n de la tecnolog\u00eda, dado que hay alternativas m\u00e1s simples y igual de efectivas, como la etiqueta , que permite al navegador solicitar un recurso sin esperar a su uso en la p\u00e1gina. Por un lado, el preload, en comparaci\u00f3n con el Server Push, genera un intercambio excesivo de paquetes (RTT), pero, por otro lado, permite evitar el env\u00edo de recursos que ya est\u00e1n en la cach\u00e9 del navegador. En general, se han se\u00f1alado diferencias en las latencias al usar Server Push y preload como no significativas. <\/p>\n

Para iniciar la precarga desde el lado servidores<\/a> se propone usar el c\u00f3digo de respuesta HTTP 103, que permite informar al cliente sobre el contenido de algunos encabezados HTTP inmediatamente despu\u00e9s de la solicitud, sin esperar a que el servidor complete todas las operaciones relacionadas con la solicitud y comience a entregar el contenido. De esta manera, se pueden comunicar sugerencias sobre elementos relacionados con la p\u00e1gina que se est\u00e1 entregando, que pueden ser precargados (por ejemplo, se pueden incluir enlaces a los CSS y JavaScript utilizados en la p\u00e1gina). Al recibir informaci\u00f3n sobre tales recursos, el navegador puede comenzar a cargarlos sin esperar a que se complete la entrega de la p\u00e1gina principal, lo que permite reducir el tiempo total de procesamiento de la solicitud. <\/p>\n

Adem\u00e1s de optimizar la carga de recursos, el mecanismo Server Push<\/a> tambi\u00e9n se pod\u00eda utilizar para la transmisi\u00f3n de datos desde el servidor al cliente, pero para estos fines, el consorcio W3C est\u00e1 desarrollando el protocolo WebTransport. El canal de comunicaci\u00f3n en WebTransport se organiza sobre HTTP\/3 utilizando el protocolo QUIC como transporte. WebTransport ofrece capacidades avanzadas como la organizaci\u00f3n de la transmisi\u00f3n en m\u00faltiples flujos, flujos unidireccionales, entrega sin considerar el orden de env\u00edo de paquetes (out-of-order), modos de entrega confiables y no confiables. <\/p>\n

Seg\u00fan estad\u00edsticas de Google, la tecnolog\u00eda Server Push no ha tenido una adopci\u00f3n significativa. A pesar de que Server Push est\u00e1 presente en la especificaci\u00f3n HTTP\/3, en la pr\u00e1ctica, muchos productos de software para servidores y clientes, incluido el navegador Chrome, no lo implementaron originalmente. En 2021, alrededor del 1.25% de los sitios que operaban con HTTP\/2 utilizaban Server Push. Este a\u00f1o, este porcentaje ha disminuido al 0.7%.
