Dost\u0119pna jest pierwsza stabilna wersja projektu nghttp3, rozwijaj\u0105cego bibliotek\u0119 w j\u0119zyku C z implementacj\u0105 protoko\u0142u HTTP\/3. Rozwijana przez ten sam projekt wersja biblioteki dla protoko\u0142u HTTP\/2 jest u\u017cywana jako baza dla modu\u0142u mod_http2, wchodz\u0105cego w sk\u0142ad serwera http Apache. Osi\u0105gni\u0119cia projektu s\u0105 tak\u017ce wykorzystywane w narz\u0119dziu Curl. Kod biblioteki jest udost\u0119pniany na licencji MIT. <\/p>\n

Standard HTTP\/3 definiuje u\u017cycie protoko\u0142u QUIC (Quick UDP Internet Connections) jako transportu dla HTTP\/2. QUIC to nadbudowa nad protoko\u0142em UDP, wspieraj\u0105ca multiplexing wielu po\u0142\u0105cze\u0144 i oferuj\u0105ca metody szyfrowania r\u00f3wnoznaczne z TLS\/SSL. Protok\u00f3\u0142 zosta\u0142 stworzony w 2013 roku przez firm\u0119 Google jako alternatywa dla zestawu TCP+TLS do zastosowa\u0144 w sieci, rozwi\u0105zuj\u0105c problemy zwi\u0105zane z du\u017cym czasem nawi\u0105zywania i uzgadniania po\u0142\u0105cze\u0144 w TCP oraz eliminuj\u0105c op\u00f3\u017anienia zwi\u0105zane z utrat\u0105 pakiet\u00f3w podczas przesy\u0142u danych. <\/p>\n

W nghttp3 dost\u0119pna jest niezale\u017cna implementacja specyfikacji RFC 9114 (HTTP\/3 na protokole QUIC), RFC 920 (technologia kompresji nag\u0142\u00f3wk\u00f3w QPACK), RFC 9220 (przesy\u0142anie WebSocket\u00f3w przez HTTP\/3) oraz RFC 9218 (rozszerzalny schemat do zarz\u0105dzania priorytetami wysy\u0142ania odpowiedzi na zapytania klient\u00f3w). Biblioteka nie jest uzale\u017cniona od okre\u015blonych stos\u00f3w QUIC i wspiera prac\u0119 na r\u00f3\u017cnych implementacjach protoko\u0142u transportowego QUIC. Projekt rozwija r\u00f3wnie\u017c w\u0142asn\u0105 implementacj\u0119 protoko\u0142u QUIC \u2014 ngtcp2, kt\u00f3ra jest stosowana domy\u015blnie. Jako backendy do szyfrowania danych w ngtcp2 wspierane s\u0105 quictls, GnuTLS, BoringSSL, Picotls i wolfSSL. R\u00f3wnocze\u015bnie z nghttp3 1.0 wydano r\u00f3wnie\u017c pierwsz\u0105 stabiln\u0105 wersj\u0119 ngtcp2 1.0.
