Riassunto (Abstract)

Questa specifica descrive un'espressione ottimizzata della semantica dell'Hypertext Transfer Protocol (HTTP), denominata HTTP versione 2 (HTTP/2). HTTP/2 consente un uso più efficiente delle risorse di rete e una latenza ridotta introducendo la compressione dei campi (Field Compression) e consentendo scambi simultanei multipli sulla stessa connessione.

Questo documento rende obsoleti gli RFC 7540 e 8740.
