Kompania NGINX njoftoi<\/a><\/noindex> p\u00ebr fillimin e testimit realizimit<\/a><\/noindex> protokolleve QUIC dhe HTTP\/3 n\u00eb serverin dhe proxy-n\u00eb http t\u00eb nginx. Zbatimi \u00ebsht\u00eb i bazuar n\u00eb draftin e 27-t\u00eb<\/a><\/noindex> t\u00eb specifikimit IETF-QUIC dhe \u00ebsht\u00eb i aksesuesh\u00ebm p\u00ebrmes nj\u00eb depo t\u00eb ve\u00e7ant\u00eb<\/a><\/noindex>, i deg\u00ebzuar nga versioni 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\u00ebshtetje p\u00ebr HTTP\/3 n\u00eb nginx \u00ebsht\u00eb sh\u00ebnuar si eksperimentale, pasi jo t\u00eb gjitha mund\u00ebsit\u00eb<\/a><\/noindex> e protokollit jan\u00eb zbatuar. Megjithat\u00eb, nginx mund t\u00eb p\u00ebrdoret tashm\u00eb p\u00ebr d\u00ebrgimin e p\u00ebrgjigjeve ndaj k\u00ebrkesave t\u00eb thjeshta HTTP\/3 mbi QUIC dhe ngarkimin\/dor\u00ebzimin e skedar\u00ebve t\u00eb m\u00ebdhenj. Nga mund\u00ebsit\u00eb e protokollit q\u00eb mungojn\u00eb p\u00ebr momentin p\u00ebrmend\u00ebn mjetet e negociat\u00ebs s\u00eb versionit t\u00eb protokollit, ECN dhe kontrollin e ngarkes\u00ebs, logjet e strukturuara, m\u00ebnyra e rikuperimit (rikuperimi QUIC, menaxhimi i fluksit dhe ngarkes\u00ebs), NAT Rebinding, adresat mobile, Server push, bashkimi i t\u00eb dh\u00ebnave (trailer). Po ashtu, \u00ebsht\u00eb ofruar vet\u00ebm mb\u00ebshtetje bazike p\u00ebr trajtimin e paketave ACK dhe menaxhimin e fluksit, e cila k\u00ebrkon p\u00ebrmir\u00ebsim. Nuk jan\u00eb marr\u00eb parasysh t\u00eb gjitha k\u00ebrkesat e standardit.<\/p>\n

P\u00ebr aktivizimin e HTTP\/3 k\u00ebrkohet q\u00eb nginx t\u00eb nd\u00ebrtohet me modulin http_v3_module dhe t\u00eb shtohet nj\u00eb drejtim shtes\u00eb
\nme p\u00ebr flamurin p\u00ebr krijimin e nj\u00eb socket-i UDP q\u00eb d\u00ebgjon. P\u00ebr shembull:<\/p>\n

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

ssl_protocols TLSv1.3; # n\u00eb QUIC k\u00ebrkohet 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 \u2018quic=\u2019:443\u2019; # shenja e disponueshm\u00ebris\u00eb QUIC
\n add_header QUIC-Status $quic; # Header me statusin e p\u00ebrdorimit t\u00eb QUIC
\n }<\/p>\n

Kujtojm\u00eb se HTTP\/3 e standardizon p\u00ebrdorimin e protokollit QUIC si transport p\u00ebr HTTP\/2. Protokolli QUIC<\/a><\/noindex> (Quick UDP Internet Connections) \u00ebsht\u00eb zhvilluar nga Google qysh n\u00eb vitin 2013 si nj\u00eb alternativ\u00eb ndaj kombinimit TCP+TLS p\u00ebr Web, duke zgjidhur problemet me koh\u00ebn e madhe t\u00eb vendosjes dhe tregtimit t\u00eb lidhjeve n\u00eb TCP dhe duke eliminuar vonesat n\u00eb rast t\u00eb humbjes s\u00eb paketa gjat\u00eb transmetimit t\u00eb t\u00eb dh\u00ebnave. QUIC p\u00ebrb\u00ebn nj\u00eb shtres\u00eb mbi protokollin UDP, duke mb\u00ebshtetur shum\u00eb lidhje dhe duke ofruar metoda enkriptimi, ekuivalente me TLS\/SSL. N\u00eb an\u00ebn e softuerit klient, mb\u00ebshtetje eksperimentale p\u00ebr HTTP\/3 tashm\u00eb \u00ebsht\u00eb shtuar n\u00eb Curl<\/a><\/noindex>, Firefox<\/a><\/noindex> dhe Chromium<\/a><\/noindex>.
