HTTP/2 supported!

kalmarsciencepark.se

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.
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.
