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