// To successfully use session resumption, ensure that the following requirements are met:
// - SessionTicketsDisabled is set to false
// - ClientSessionCache is non-nil
// - For TLS 1.2, SessionTicketExtension is non-nil
// - For TLS 1.3, PreSharedKeyExtension is non-nil

// There may be cases where users enable session resumption (SessionTicketsDisabled: false && ClientSessionCache: non-nil), but they do not provide SessionTicketExtension or PreSharedKeyExtension in the ClientHelloSpec. This could be intentional or accidental.

// By default, utls throws an exception in such scenarios. Set this to true to skip the resumption and suppress the exception.
