CLIENT SIDE CACHE VISIBILITY WITH TLS SESSION TICKETS

Abstract:

Among other things, this document describes systems, devices, and methods for using TLS session resumption tickets to store and manage information about objects that a server or a set of servers has previously delivered to a client and therefore that the client is likely to have in client-side cache. When communicated to a server later, this information can be used to drive server decisions about whether to push an object to a client, e.g., using an HTTP/2 server push function or the like, or whether to send an early hint to the client about anobject.
