<p dir="auto">This introduces a new set of database functions that should be set by servers supporting 0rtt. Why not re-use the existing <code>gnutls_db</code> subsystem to store such entries? From the app developer perspective there will be minimal changes to an existing server application. What do you think is the main benefit from this new api?</p>
