ssl.SSLContext.set_servername_callback¶

SSLContext.set_servername_callback(method)¶

This sets a callback that will be called when a server name is provided by the SSL/TLS client in the SNI extension.

If the argument is None then the callback is disabled. The method is called with the SSLSocket, the server name as a string, and the SSLContext object. See RFC 6066 for details of the SNI extension.
