Google tau ceeb toom tias kev txhawb nqa rau Server Push thev naus laus zis yuav raug cuam tshuam hauv kev tso tawm Chrome 106, tau teem sijhawm rau lub Cuaj Hlis 27th. Cov kev hloov pauv tseem yuav cuam tshuam rau lwm qhov browsers raws li Chromium codebase. Server Push thev naus laus zis tau txhais hauv HTTP / 2 thiab HTTP / 3 tus qauv, thiab tso cai rau lub server xa cov peev txheej mus rau tus neeg siv khoom yam tsis tau tos rau lawv qhov kev thov meej.

Feem ntau, qhov sib txawv ntawm latency thaum siv Server Push thiab preload tau sau tseg tias tsis tseem ceeb.
Txhawm rau pib ua ntej kev thauj khoom ntawm tus neeg rau zaub mov sab, nws tau thov kom siv HTTP cov lus teb chaws 103, uas tso cai rau koj qhia tus neeg siv khoom txog cov ntsiab lus ntawm qee qhov HTTP headers tam sim ntawd tom qab qhov kev thov, tsis tas tos cov neeg rau zaub mov kom tiav tag nrho cov haujlwm ntsig txog. qhov kev thov thiab pib ua haujlwm rau cov ntsiab lus. Ib yam li ntawd, koj tuaj yeem muab cov lus qhia txog cov ntsiab lus ntsig txog nplooj ntawv tau txais kev pabcuam uas tuaj yeem raug thauj khoom ua ntej (piv txwv li, koj tuaj yeem muab txuas rau CSS thiab JavaScript siv rau ntawm nplooj ntawv). Tom qab tau txais cov ntaub ntawv hais txog cov peev txheej zoo li no, tus browser tuaj yeem pib rub tawm lawv yam tsis tau tos rau nplooj ntawv tseem ceeb kom ua tiav, uas txo cov sijhawm thov tag nrho.

Txoj kev sib txuas lus hauv WebTransport tau teeb tsa saum HTTP / 3 siv QUIC raws tu qauv ua kev thauj mus los. WebTransport muaj cov yam ntxwv zoo li no xws li kev teeb tsa kev sib kis mus rau ntau qhov kwj, unidirectional kwj, kev xa khoom yam tsis xav txog qhov kev txiav txim uas cov pob ntawv raug xa mus (tawm-ntawm-kev txiav txim), txhim khu kev qha thiab tsis tuaj yeem xa tawm hom.
