# HTTP/2 Analyzer PRO
|Category||Severity||Time To Fix|
|🚀 Performance||Major||10 minutes|
This analyzer confirms whether your application supports the HTTP/2 protocol.
If your application is served over HTTPS connections, HTTP/2 can provide a nice performance boost with request/response multiplexing, header compression and faster TLS handshakes.
# Easy Way To Confirm
To confirm that this is an issue, you can use
curl to fire the following request to your application:
curl -I -L https://myapp.com
After running the above command, check for the first line in the output that displays the HTTP protocol version.
# How To Fix
If you serve your application through a CDN or load balancer service, you will need to make sure that HTTP/2 is enabled on your service.
If you serve your app directly via a web server, make sure that HTTP/2 is enabled and configured on your web server. The references listed below may help out on how to do this.
# Skip Condition
This analyzer is skipped if your application does not have an HTTPS app URL or if the
curl PHP extension is not installed (or does not support HTTP/2). Modern browsers only support HTTP/2 over HTTPS connections and this is why, this analyzer is skipped for non-HTTPS apps.
