I-Google yethule izinhlelo zayo uphetheni ukususa usekelo lwe-Server Push nge-Chrome 106, (okuhlelelwe uSepthemba 27) nokuthi ushintsho luzophinda luthinte ezinye iziphequluli ngokusekelwe kusisekelo sekhodi ye-Chromium.
Kulabo abangabazi ubuchwepheshe be-Server Push, kufanele ukwazi lokho ichazwa kumazinga e-HTTP/2 kanye ne-HTTP/3, futhi ivumela iseva ukuthi ithumele izinsiza kuklayenti ngaphandle kokulinda ukuthi zicelwe ngokucacile.
Kufanele kube ngalendlela iseva ingasheshisa ukulayisha kwekhasi, njengoba amafayela e-CSS, imibhalo, nezithombe ezidingekayo ukuze kunikezwe ikhasi zizovele zidluliselwe eceleni kwakho ngesikhathi iklayenti likucela.
Ukuhlaziywa kokusetshenziswa kwe-HTTP/2 Server Push kunemiphumela exubile ( Chrome , Akamai ), engenayo inzuzo ecacile yokusebenza futhi ezimweni eziningi ukwehla kokusebenza.
I-Push ayizange isetshenziswe kumaseva amaningi e-HTTP/3 namakhasimende, nakuba ifakiwe kufayela le-. Esikhathini esiningi sewebhu kusetshenziswa i-HTTP/3 entsha, i-Push isivele iyekisiwe. Ukuqalisa kabusha lokho kuhlaziya kamuva nje, sibona ukuthi ukusekelwa okungu-1,25% kwe-HTTP/2 ngamasayithi kwehle kwaya ku-0,7%.
Njengesizathu sokuphela kokusekelwa kubaluliwe ubunzima obungadingekile bokuqaliswa kobuchwepheshe uma kukhona ezinye izindlela ezilula nezingasebenzi kahle, njengelebula , lapho isiphequluli singacela khona insiza ngaphandle kokulinda ukuthi isetshenziswe ekhasini. Ngakolunye uhlangothi, ukulanda kuqala, uma kuqhathaniswa ne-Server Push, ikhiqiza ukushintshaniswa kwephakethe okwengeziwe (RTT), kodwa ngakolunye uhlangothi, igwema ukuthumela izinsiza esezivele zikunqolobane yesiphequluli. Ngokuvamile, umehluko ekubambezelekeni uma usebenzisa i-Server Push kanye nokulayisha kuqala kumakwa njengokunganaki.
Ukuze uqalise ukulayisha okusebenzayo ohlangothini lweseva, kuhlongozwa ukusebenzisa ikhodi yokuphendula ye-HTTP engu-103, ekuvumela ukuthi wazise iklayenti ngokuqukethwe kwezinye izihloko ze-HTTP ngokushesha ngemva kwesicelo, ngaphandle kokulinda iseva ukuthi yenze yonke imisebenzi ehlobene. ngesicelo bese uqala ukunikeza okuqukethwe.
103 Amacebiso Angaphambi Kwesikhashana iyindlela ehlukile ethambekele kakhulu enephutha enezinzuzo eziningi ezifana ne-Push, kanye nokubi okumbalwa kakhulu. Esikhundleni sokuthi iseva ithumele izinsiza, i-103 Early Hints ithumela kuphela amacebiso kusiphequluli sezinsiza esingazuza ngokuzicela ngokushesha. Lokhu kushiya isiphequluli silawula ukunquma ukuthi siyazidinga noma cha, isibonelo uma sesivele sinalezo zinsiza kunqolobane ye-HTTP.
Ukulayishwa kuqala kwensiza ebalulekile kungenye indlela evumela ikhasi nesiphequluli ukuthi zisebenze ndawonye ukuze zilayishe izinsiza ezibalulekile ngaphambi kwesikhathi ekulayisheni kwekhasi.
Ngokufanayo, inganikeza izeluleko mayelana nezinto ezihlobene nekhasi elinikeziwe, elingalayishwa kuqala (isibonelo, izixhumanisi ze-CSS ne-JavaScript ezisetshenziswe ekhasini zinganikezwa). Ngemva kokuthola ulwazi mayelana nezinsiza ezinjalo, isiphequluli singaqala ukuzilanda ngaphandle kokulinda ukuphela kokubuyiselwa kwekhasi eliyinhloko, okunciphisa isikhathi esiphelele sokucubungula isicelo.
Ngaphezu kokwenza kahle umthwalo wezinsiza, indlela ye-Server Push ingase isetshenziselwe ukudlulisa idatha isuka kuseva iye kuklayenti, kodwa ngalezi zinhloso, i-W3C consortium ithuthukisa iphrothokholi ye-WebTransport. Isiteshi sokuxhumana ku-WebTransport sihlelwa nge-HTTP/3 sisebenzisa iphrothokholi ye-QUIC njengezokuthutha, i-WebTransport inikeza izici ezithuthukile ezifana nokusakaza okuningi, ukusakaza ngendlela eyodwa, ukulethwa ngaphandle kwe-oda, izindlela zokulethwa ezithembekile nezingathembekile.
Ngokwezibalo ze-Google, ubuchwepheshe be-Server Push abukatholi ukusatshalaliswa okwanele. Nakuba i-Server Push ikhona ekucacisweni kwe-HTTP/3, empeleni imikhiqizo eminingi yamaklayenti nesofthiwe yesiphakeli, okuhlanganisa isiphequluli se-Chrome, ayizange iyisebenzise ngokwemvelo. Ngo-2021, cishe u-1,25% wamawebhusayithi asebenzisa i-HTTP/2 asebenzisa i-Server Push. Kulo nyaka, lesi sibalo sehle safinyelela ku-0,7%.
Okokugcina uma unentshisekelo yokwazi kabanzi ngakho, ungabheka imininingwane kufayela le- isixhumanisi esilandelayo.
