How to check wether http2 is implemented and working on my website?

Question

I want to check whether http/2 is implemented on my website or not. When I check through https://tools.keycdn.com/ it says http2 is implemented but the typing curl -I in cmd gives the ouptut:

HTTP/1.1 200 OK
Date: Fri, 25 Jan 2019 17:02:45 GMT
Server: Apache
Pragma: no-cache
Cache-Control: max-age=0, must-revalidate, no-cache, no-store
Expires: Thu, 25 Jan 2018 17:02:47 GMT
X-Magento-Tags: FPC
X-Content-Type-Options: nosniff
X-XSS-Protection: 1; mode=block
X-Frame-Options: SAMEORIGIN
...

Which one is correct is http2 implemented or not ?

Are you sure curl is requesting via HTTP2?

try using --http2, from this page on the curl website:

curl offers the --http2 command line option to enable use of HTTP/2.

I just typed that into the cmd and that returns : curl: (1) Unsupported protocol – Muhammad Hamza Shujaat Jan 26 '19 at 05:06

So you are using an older version of curl that doesn’t support HTTP/2, hence why it falls back to HTTP/1.1 hence why you are seeing a difference between that and the online tool. – Barry Pollard Jan 26 '19 at 10:30
