HTTP/2 supported!

Fantastic! This server supports HTTP/2.

ALPN: No ALPN, No NPN
This server does not support any of the protocol negotiation methods. Unless the client explicitly makes an HTTP/2 request, HTTP/2 will not be used by default, and may require additional round trips.
PUSH: No
We could not find any resources being pushed. If there are no resources that might benefit from HTTP/2 Push feature, ignore this.
