TLS Ticket Requests
RFC 9149, “TLS Ticket Requests”, is a Proposed Standard document published in April 2022 by T. Pauly, D. Schinazi, C.A. Wood. The canonical text is published by the RFC Editor.
Abstract
TLS session tickets enable stateless connection resumption for clients without server-side, per-client state. Servers vend an arbitrary number of session tickets to clients, at their discretion, upon connection establishment. Clients store and use tickets when resuming future connections. This document describes a mechanism by which clients can specify the desired number of tickets needed for future connections. This extension aims to provide a means for servers to determine the number of tickets to generate in order to reduce ticket waste while simultaneously priming clients for future connection attempts.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
