US Patent 10581948 Client side cache visibility with TLS session tickets

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 an object.
