@deftypefun {int} {gnutls_session_ticket_enable_server} (gnutls_session_t @var{session}, const gnutls_datum_t * @var{key})
@var{session}: is a @code{gnutls_session_t}  type.

@var{key}: key to encrypt session parameters.

Request that the server should attempt session resumption using
session tickets, i.e., by delegating storage to the client.
 @code{key} must be initialized using @code{gnutls_session_ticket_key_generate()} .
To avoid leaking that key, use @code{gnutls_memset()}  prior to
releasing it.

The default ticket expiration time can be overridden using
@code{gnutls_db_set_cache_expiration()} .

@strong{Returns:} On success, @code{GNUTLS_E_SUCCESS}  (0) is returned, or an
error code.

@strong{Since:} 2.10.0
