core: HTTP trailers could be used to replace HTTP headers
late during request processing, potentially undoing or

*) mod_ssl: New directive SSLSessionTickets (On|Off).
The directive controls the use of TLS session tickets (RFC 5077),

recreation mechanism is available currently. Therefore using session
tickets without restarting the web server with an appropriate frequency
(e.g. daily) compromises perfect forward secrecy. [Rainer Jung]
