RFC 9149: TLS Ticket Requests

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.
