Lub vas sab kua nplaum (feem ntau yog hu ua "cookie") yog ib qho me me ntawm cov ntaub ntawv uas lub website nyob hauv ib tus neeg siv qhov web browser . Thaum ib tus neeg twg xa ib lub vev xaib, cov khoom qab zib tuaj yeem qhia qhov browser cov lus qhia txog lawv mus xyuas los yog yav dhau los. Cov ntaub ntawv no tuaj yeem tso cai rau lub site kom nco tau cov kev xav tau uas tau teem rau lub sijhawm dhau los lossis nws tuaj yeem rov qab ua kom dhau los ntawm ib qho dhau los.
Koj puas tau mus rau lub vev xaib E-commerce thiab ntxiv ib yam khoom rau lub laub yuav khoom, tab sis tsis muaj peev xwm ua tiav cov nqi? Yog tias koj rov qab tuaj rau lub tsev kawm ntawv tom qab ntawd, tsuas yog mus nrhiav koj cov khoom tos koj hauv lub tsheb ntawd, ces koj tau pom ib qho khoom qab zib rau hauv ntawv.
Qhov Cim Ntawm Cov Nyiaj Caw
Qhov loj ntawm lub kua nplaum HTTP (uas yog lub npe tiag tiag ntawm lub ncuav qab zib) yog txiav txim los ntawm tus neeg siv khoom siv. Thaum koj ntsuas qhov luaj li cas ntawm koj lub khoom qab zib, koj yuav tsum suav cov ntawv bytes hauv tag nrho lub npe = tus nqi khub, nrog rau kev sib npaug.
Raws li lub RFC 2109, lub ncuav qab zib lub web yuav tsum tsis pub tsawg dua los ntawm cov neeg siv cov neeg siv, tiam sis qhov peev xwm ntawm qhov browser lossis neeg siv tus neeg sawv cev yuav tsum tsawg kawg yog 4096 bytes ib lub khoom qab zib. Cov kev txwv no yog siv rau lub npe = tus nqi ntawm cov cookie xwb.
Qhov no txhais tau hais tias yog koj sau ntawv cog qaub thiab cov khoom qab zib tsawg dua 4096 bytes, ces nws yuav raug txhawb los ntawm txhua tus browser thiab neeg siv tus neeg saib xyuas uas ua raws li lub RFC.
Nco ntsoov tias qhov no yog qhov tsawg kawg nkaus raws li RFC. Qee cov browsers yuav txhawb cov ncuav qab zib ntev, tab sis kom tsis raug mob, koj yuav tsum khaws koj cov ncuav qab zib rau hauv 4093 bytes. Muaj ntau cov xwm txheej (xws li cov ntawv xov xwm yav dhau los ntawm no) tau hais tias nyob hauv 4095 bytes yuav tsum txaus los xyuas kom paub meej qhov kev pab cuam browser, tab sis qee qhov kev ntsuam xyuas pom tau tias tej yam khoom siv tshiab, zoo li lub iPad 3, tuaj yeem qis dua 4095.
Kev Xeem rau Koj Tus Kheej
Ib txoj hauv kev zoo tshaj plaws los txiav txim siab txog kev txwv cov cuav hauv web sib txawv hauv kev sib txawv nws yuav siv qhov kev sib tw Browser Limits.
Khiav ua qhov kev xeem no hauv ob peb lub browsers ntawm kuv lub computer, Kuv tau txais cov lus qhia txuas mus ntxiv rau qhov tseeb versions ntawm cov browsers:
- Google Chrome - 4096 bytes
- Internet Explorer - 5117 bytes
- Firefox - 4097 bytes
