Starting with version 6.0, PNS supports session reuse in SSL and TLS connections. PNS supports both session identifiers (RFC 5246) and session tickets (RFC 5077). Note that session tickets can be used only in TLS connections. Unless explicitly disabled in the configuration of the Encryption policy (for details, see Section 5.5, Module Encryption), PNS attempts to use session tickets, and automatically falls back to using session identifiers if needed.
