jdk.tls.server.enableSessionTicketExtension determines if the server will provide stateless session tickets, if the client supports it, as described in RFC 5077 and RFC 8446. a stateless session ticket contains the encrypted server's state which saves server resources. jdk.tls.client.enableSessionTicketExtension determines if the client will send an extension in the ClientHello in the pre-TLS 1.3. This extension allows the client to accept the server's session state for Server Side stateless resumption (RFC 5077). Setting the property to "false" turns this off, by default it is true. For TLS 1.3, the system property is not needed as this support is part of the spec. jdk.tls.server.sessionTicketTimeout determines how long a session in the server cache or the stateless resumption tickets are available for use. The value set by the property can be modified by SSLSessionContext.setSessionTimeout() during runtime.
