Bol zverejnen\u00fd kompaktn\u00fd HTTP server hinsightd, ktor\u00fd vynik\u00e1 pou\u017eit\u00edm rozhrania asynchr\u00f3nneho vstupu\/v\u00fdstupu io_uring poskytovan\u00e9ho v jadre Linux. Server podporuje protokol HTTP\/1.1 a je navrhnut\u00fd tak, aby m\u00e1lo spotrebov\u00e1val zdroje, pri\u010dom poskytuje po\u017eadovan\u00fa funkcionalitu. Napr\u00edklad, hinsightd podporuje TLS, reverzn\u00e9 proxy (rproxy), caching dynamicky generovan\u00e9ho obsahu v miestnom FS, kompresiu odosielan\u00fdch d\u00e1t na po\u017eiadanie, re\u0161tart bez preru\u0161enia existuj\u00facich spojen\u00ed, pripojenie dynamick\u00fdch spracovate\u013eov po\u017eiadaviek pomocou mechanizmov FastCGI a CGI. K\u00f3d projektu je nap\u00edsan\u00fd v programovacom jazyku C a je distribuovan\u00fd pod licenciou BSD. <\/p>\n
