<\/p>\nJu ndoshta jeni njohur tashm\u00eb me HTTP. \u00cbsht\u00eb protokolli q\u00eb b\u00ebn t\u00eb mundur internetin modern. Pa t\u00eb, nuk do t\u00eb mund t\u00eb kalonit or\u00eb t\u00eb t\u00ebra n\u00eb Instagram, Facebook, apo edhe k\u00ebt\u00eb blog, k\u00ebshtu q\u00eb t\u00eb gjith\u00eb i detyrohemi shum\u00eb.<\/p>\n
Ajo q\u00eb mund t\u00eb mos dini \u00ebsht\u00eb se protokolli n\u00eb p\u00ebrdorim tani \u00ebsht\u00eb HTTP\/2, dhe n\u00eb fakt ka nj\u00eb version t\u00eb ri tashm\u00eb. HTTP\/3 \u00ebsht\u00eb nj\u00eb pun\u00eb e madhe. Ai ka vendosur nj\u00eb standard t\u00eb ri p\u00ebr ueb-in, duke kaluar nga nj\u00eb Protokoll i Kontrollit t\u00eb Transmisionit (TCP) n\u00eb Quick UPD Internet Connections (QUIC). N\u00ebse nuk e dini se \u00e7far\u00eb do t\u00eb thot\u00eb kjo, mos u shqet\u00ebsoni – ne do ta shpjegojm\u00eb at\u00eb n\u00eb nj\u00eb moment.<\/p>\n
N\u00eb k\u00ebt\u00eb artikull, ne do t\u00eb analizojm\u00eb se \u00e7far\u00eb \u00ebsht\u00eb HTTP dhe si funksionon. Ne gjithashtu do t’ju prezantojm\u00eb me HTTP\/3 dhe do t\u00eb diskutojm\u00eb se \u00e7far\u00eb sjell n\u00eb tavolin\u00eb. Le t\u00eb flasim p\u00ebr protokollet!<\/p>\n
HTTP p\u00ebrfshin nj\u00eb grup rregullash q\u00eb rregullojn\u00eb m\u00ebnyr\u00ebn se si faqet e internetit p\u00ebrdorin dhe transferojn\u00eb skedar\u00eb te p\u00ebrdoruesit, ose m\u00eb konkretisht te shfletuesit e tyre. Sipas k\u00ebtij modeli, shfletuesi juaj b\u00ebhet nj\u00eb “klient” q\u00eb lidhet me server\u00ebt duke p\u00ebrdorur “daemons”.<\/p>\n
Nj\u00eb daemon \u00ebsht\u00eb nj\u00eb program i nd\u00ebrtuar p\u00ebr t’iu p\u00ebrgjigjur ‘k\u00ebrkesave’ HTTP, t\u00eb cilat ndodhin sa her\u00eb q\u00eb hyni n\u00eb nj\u00eb faqe interneti. N\u00eb praktik\u00eb, i gjith\u00eb procesi ndodh pa probleme n\u00eb sfond sa her\u00eb q\u00eb klikoni n\u00eb nj\u00eb URL ose shkruani nj\u00eb adres\u00eb.<\/p>\n
Megjithat\u00eb, n\u00eb shumic\u00ebn e rasteve, \u00e7do faqe interneti q\u00eb vizitoni p\u00ebrfshin shfletuesin tuaj duke b\u00ebr\u00eb dhjet\u00ebra k\u00ebrkesa n\u00eb sfond.\u00a0I gjith\u00eb ky aktivitet ndodh mbi TCP. Ky \u00ebsht\u00eb protokolli q\u00eb trajton shp\u00ebrndarjen e t\u00eb dh\u00ebnave nga nj\u00eb adres\u00eb IP n\u00eb tjetr\u00ebn, e cila mbulon si server\u00ebt ashtu edhe klient\u00ebt. Ne kemi p\u00ebrdorur TCP p\u00ebr komunikime p\u00ebr m\u00eb shum\u00eb se 40 vjet tani.<\/p>\n
TCP e b\u00ebn mir\u00eb pun\u00ebn e tij, por kjo nuk do t\u00eb thot\u00eb se nuk ka vend p\u00ebr p\u00ebrmir\u00ebsim. K\u00ebtu hyn QUIC dhe kjo \u00ebsht\u00eb ajo q\u00eb do t\u00eb mbulojm\u00eb m\u00eb pas.<\/p>\n
Si\u00e7 e p\u00ebrmend\u00ebm m\u00eb her\u00ebt, ka m\u00eb shum\u00eb se nj\u00eb version t\u00eb HTTP. Standardi p\u00ebr momentin \u00ebsht\u00eb HTTP\/2, me mb\u00ebshtetje p\u00ebr versionin e tret\u00eb q\u00eb tashm\u00eb \u00ebsht\u00eb shfaqur n\u00eb disa versione, duke p\u00ebrfshir\u00eb Chrome Canary dhe Firefox Nightly.<\/p>\n
Dallimi kryesor midis HTTP\/2 dhe HTTP\/3 zbret n\u00eb protokollet TCP dhe QUIC. HTTP\/3 b\u00ebn kalimin n\u00eb QUIC, i cili premton nj\u00eb rritje t\u00eb konsiderueshme t\u00eb performanc\u00ebs p\u00ebr shumic\u00ebn e ‘links’. Dallimi midis k\u00ebtyre protokolleve zbret n\u00eb “shtr\u00ebngime duarsh” (ang. handshakes).<\/p>\n
Kur dy pika t\u00eb nj\u00eb rrjeti shk\u00ebmbejn\u00eb sinjale p\u00ebr t\u00eb krijuar nj\u00eb lidhje, kjo quhet shtr\u00ebngim duarsh. Me protokollin TCP, shfletuesi juaj duhet t\u00eb krijoj\u00eb tre shtr\u00ebngime duarsh p\u00ebr t\u00eb b\u00ebr\u00eb nj\u00eb lidhje t\u00eb vlefshme. K\u00ebtu \u00ebsht\u00eb nj\u00eb animacion i dobish\u00ebm nga Google q\u00eb tregon se si zhvillohet procesi i shtr\u00ebngimit t\u00eb duarve mbi TCP kundrejt QUIC.<\/p>\n
<\/p>\n
Sa m\u00eb shum\u00eb duar t\u00eb keni p\u00ebr t\u00eb shtr\u00ebnguar, aq m\u00eb shum\u00eb koh\u00eb duhet p\u00ebr t\u00eb krijuar nj\u00eb lidhje. Duke p\u00ebrdorur QUIC, shfletuesi juaj duhet t\u00eb shtr\u00ebngoj\u00eb vet\u00ebm nj\u00eb dor\u00eb. Le t\u00eb flasim p\u00ebr at\u00eb q\u00eb do t\u00eb thot\u00eb p\u00ebr ju.<\/p>\n
Kalimi nga TCP n\u00eb QUIC vjen me p\u00ebrfitime t\u00eb shumta t\u00eb prekshme, duke p\u00ebrfshir\u00eb:<\/p>\n
Disa host\u00eb t\u00eb uebit tashm\u00eb ofrojn\u00eb server\u00eb me HTTP\/3 gjithashtu. N\u00ebse vizitor\u00ebt e faqes suaj p\u00ebrdorin shfletues q\u00eb mb\u00ebshtesin protokollin e ri, ata duhet t\u00eb g\u00ebzojn\u00eb koh\u00eb t\u00eb reduktuara t\u00eb ngarkimit.<\/p>\n
Shum\u00eb sh\u00ebrbime, t\u00eb tilla si Cloudflare, kan\u00eb shtuar tashm\u00eb mb\u00ebshtetjen HTTP\/3 p\u00ebr p\u00ebrdoruesit e tyre, dhe k\u00ebtu n\u00eb Hostinkos Hosting ne nuk jemi prapa. Mund t\u00eb regjistroheni p\u00ebr nj\u00eb plan hostimi biznes premium me aktivizim HTTP\/3 q\u00eb tani.<\/p>\n
Sa i p\u00ebrket arsyes pse HTTP\/3, kalimi nga protokolli TCP n\u00eb QUIC do t\u00eb thot\u00eb se interneti do t\u00eb b\u00ebhet shum\u00eb m\u00eb i shpejt\u00eb. Uebsajtet do t\u00eb marrin m\u00eb pak koh\u00eb p\u00ebr t’u ngarkuar, memet do t\u00eb shfaqen m\u00eb shpejt, sh\u00ebrbimet do t\u00eb p\u00ebrmir\u00ebsohen.<\/p>\n","protected":false},"excerpt":{"rendered":"
