/* The servername extension is treated as follows:
379
- Only the hostname type is supported with a maximum length of 255.
380
- The servername is rejected if too long or if it contains zeros,
381
in which case an fatal alert is generated.
382
- The servername field is maintained together with the session cache.
383
- When a session is resumed, the servername call back invoked in order
384
to allow the application to position itself to the right context.
385
- The servername is acknowledged if it is new for a session or when
386
it is identical to a previously used for the same session.
387
Applications can control the behaviour. They can at any time
388
set a 'desirable' servername for a new SSL object. This can be the
389
case for example with HTTPS when a Host: header field is received and
390
a renegotiation is requested. In this case, a possible servername
391
presented in the new client hello is only acknowledged if it matches
392
the value of the Host: field.
393
- Applications must use SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION
394
if they provide for changing an explicit servername context for the session,
395
i.e. when the session has been established with a servername extension.
396
- On session reconnect, the servername extension may be absent.
