Kompania NGINX njoftoi<\/a><\/noindex> n\u00eb lidhje me fillimin e testimit implementation<\/a><\/noindex> t\u00eb protokolleve QUIC dhe HTTP\/3 n\u00eb serverin dhe proksin\u00eb HTTP nginx. Zbatimi \u00ebsht\u00eb i bazuar n\u00eb draftin 27<\/a><\/noindex> e specifikimit IETF-QUIC dhe \u00ebsht\u00eb i disponuesh\u00ebm p\u00ebrmes nj\u00eb repozitari t\u00eb ve\u00e7ant\u00eb<\/a><\/noindex>, i pasuar nga l\u00ebshimi 1.19.0. Kodi shp\u00ebrndahet n\u00ebn licenc\u00ebn BSD dhe nuk p\u00ebrputhet me implementimin e propozuar m\u00eb par\u00eb<\/a><\/noindex> t\u00eb HTTP\/3 p\u00ebr nginx nga kompania Cloudflare, e cila \u00ebsht\u00eb nj\u00eb projekt i ve\u00e7ant\u00eb.<\/p>\n

Mb\u00ebshtetja p\u00ebr HTTP\/3 n\u00eb nginx \u00ebsht\u00eb e etiketuar si eksperimentale, pasi jo t\u00eb gjitha mund\u00ebsit\u00eb<\/a><\/noindex> e protokollit jan\u00eb zbatime. Megjithat\u00eb, nginx tashm\u00eb mund t\u00eb p\u00ebrdoret p\u00ebr t\u00eb d\u00ebrguar p\u00ebrgjigje n\u00eb k\u00ebrkesa t\u00eb thjeshta HTTP\/3 mbi QUIC dhe p\u00ebr t\u00eb ngarkuar\/dh\u00ebn\u00eb skedar\u00eb t\u00eb m\u00ebdhenj. Nga mund\u00ebsit\u00eb e protokollit q\u00eb nuk jan\u00eb akoma t\u00eb disponueshme, p\u00ebrfshihen mjete p\u00ebr t\u00eb negociuar versionin e protokollit, ECN dhe kontrollin e ngarkes\u00ebs, logje t\u00eb strukturuara, modalityn e rikuperimit (rikuperimi QUIC, menaxhimi i rrjedh\u00ebs dhe ngarkes\u00ebs), NAT Rebinding, adresat mobile, Server push, bashk\u00ebngjitja e t\u00eb dh\u00ebnave (trailer). Gjithashtu, ofrohet vet\u00ebm mb\u00ebshtetje bazike e p\u00ebrpunimit t\u00eb paketeve ACK dhe menaxhimit t\u00eb rrjedh\u00ebs, e cila k\u00ebrkon p\u00ebrmir\u00ebsim. Jo t\u00eb gjitha k\u00ebrkesat e standardit jan\u00eb marr\u00eb n\u00eb konsiderat\u00eb.<\/p>\n

P\u00ebr t\u00eb aktivizuar HTTP\/3, nevojitet t\u00eb kompiloni nginx me modulin http_v3_module dhe t\u00eb shtoni drejtorin\u00eb shtes\u00eb
\n\u00ablisten\u00bb me flamurin \u00abhttp3\u00bb p\u00ebr t\u00eb krijuar nj\u00eb socket UDP d\u00ebgjues. P\u00ebr shembull:<\/p>\n

server {
\n listen 443 ssl; # TCP-socket p\u00ebr HTTP\/1.1
\n listen 443 http3 reuseport; # UDP-socket p\u00ebr QUIC+HTTP\/3<\/p>\n

ssl_protocols TLSv1.3; # n\u00eb QUIC \u00ebsht\u00eb i domosdosh\u00ebm TLS 1.3
\n ssl_certificate ssl\/www.example.com.crt;
\n ssl_certificate_key ssl\/www.example.com.key;<\/p>\n

add_header Alt-Svc 'quic=\u00bb:443'; # treguesi i disponueshm\u00ebris\u00eb s\u00eb QUIC
\n add_header QUIC-Status $quic; # Header me statusin e p\u00ebrdorimit t\u00eb QUIC
\n }<\/p>\n

Le t\u00eb p\u00ebrkujtojm\u00eb se HTTP\/3 standardizon p\u00ebrdorimin e protokollit QUIC si transport p\u00ebr HTTP\/2. Protokolli QUIC<\/a><\/noindex> (Quick UDP Internet Connections) q\u00eb nga viti 2013 zhvillohet nga kompania Google si nj\u00eb alternativ\u00eb p\u00ebr lidhjen TCP+TLS p\u00ebr Web, e cila zgjidh problemet me koh\u00ebn e gjat\u00eb t\u00eb vendosjes dhe negociat\u00ebs s\u00eb lidhjeve n\u00eb TCP dhe eliminon vonesat gjat\u00eb humbjes s\u00eb paketeve gjat\u00eb transmetimit t\u00eb t\u00eb dh\u00ebnave. QUIC \u00ebsht\u00eb nj\u00eb shtres\u00eb mbi protokollin UDP, q\u00eb mb\u00ebshtet shum\u00eb lidhje dhe siguron metoda enkriptimi, ekuivalente me TLS\/SSL. N\u00eb an\u00ebn e klient\u00ebve, mb\u00ebshtetje eksperimentale p\u00ebr HTTP\/3 \u00ebsht\u00eb shtuar tashm\u00eb n\u00eb Curl<\/a><\/noindex>, Firefox<\/a><\/noindex> dhe Chromium<\/a><\/noindex>.
