Online tool to check server HTTP/2, ALPN, and Server-push support.

HTTP/2 supported!

Fantastic! This server supports HTTP/2.

ALPN: No ALPN, But NPN supported
This server supports Next Protocol Negotiation, but not ALPN. Browsers are dropping support for NPN, and it is becoming an obsolete technology. Opt to use ALPN.
We could not find any resources being pushed. If there are no resources that might benefit from HTTP/2 Push feature, ignore this.
