 ALPN (Application-Layer Protocol Negotiation Extension), NPN (Next
 Protocol Negotiation) and SNI (Server Name Indication) are TLS
-handshake extensions allowing you:

-  * ALPN/NPN - to use one TLS server for multiple protocols (HTTP, SPDY, HTTP/2)
-  * SNI - to use one TLS server for multiple hostnames with different SSL
