WebApr 11, 2024 · This allows for 0-RTT, where the first HTTP request can be sent along with the QUIC/TLS handshake, removing the TLS handshake’s waiting time. It is important to note that session resumption and 0-RTT are actually TLS features that were already present in some form in TLS 1.2 and are now fully fledged in TLS 1.3. WebTLS 1.3 added support for 0-RTT, allowing to send application data in the first packet of the TLS handshake. which makes it possible to establish a encrypted connection and send the application over TCP in one packet.
