.. versionadded:: 3.3
.. method:: SSLContext.set_servername_callback(server_name_callback)
Register a callback function that will be called after the TLS Client Hello
handshake message has been received by the SSL/TLS server when the TLS client
specifies a server name indication. The server name indication mechanism
is specified in :rfc:`6066` section 3 - Server Name Indication.
Only one callback can be set per ``SSLContext``. If *server_name_callback*
is ``None`` then the callback is disabled. Calling this function a
subsequent time will disable the previously registered callback.
The callback function, *server_name_callback*, will be called with three
arguments; the first being the :class:`ssl.SSLSocket`, the second is a string
that represents the server name that the client is intending to communicate
and the third argument is the original :class:`SSLContext`. The server name
argument is the IDNA decoded server name.
A typical use of this callback is to change the :class:`ssl.SSLSocket`'s
:attr:`SSLSocket.context` attribute to a new object of type
:class:`SSLContext` representing a certificate chain that matches the server
name.
Due to the early negotiation phase of the TLS connection, only limited
methods and attributes are usable like
:meth:`SSLSocket.selected_npn_protocol` and :attr:`SSLSocket.context`.
:meth:`SSLSocket.getpeercert`, :meth:`SSLSocket.getpeercert`,
:meth:`SSLSocket.cipher` and :meth:`SSLSocket.compress` methods require that
the TLS connection has progressed beyond the TLS Client Hello and therefore
will not contain return meaningful values nor can they be called safely.
The *server_name_callback* function must return ``None`` to allow the
the TLS negotiation to continue. If a TLS failure is required, a constant
:const:`ALERT_DESCRIPTION_* <ALERT_DESCRIPTION_INTERNAL_ERROR>` can be
returned. Other return values will result in a TLS fatal error with
:const:`ALERT_DESCRIPTION_INTERNAL_ERROR`.
If there is a IDNA decoding error on the server name, the TLS connection
will terminate with an :const:`ALERT_DESCRIPTION_INTERNAL_ERROR` fatal TLS
alert message to the client.
If an exception is raised from the *server_name_callback* function the TLS
connection will terminate with a fatal TLS alert message
:const:`ALERT_DESCRIPTION_HANDSHAKE_FAILURE`.
This method will raise :exc:`NotImplementedError` if the OpenSSL library
had OPENSSL_NO_TLSEXT defined when it was built.
