Cloudflare: How to enable HTTP/3
This article shows you how to enable HTTP/3 for a website that using Cloudflare.
Why HTTP/3?
HTTP/3 is the third major version of the Hypertext Transfer Protocol that will replace HTTP and HTTP/2 in the future. It can accelerate your website as well as make it more secure.
Check if your website using HTTP/3 or not
There are several free online tools that can help you check whether your website is using HTTP/3 or not. I strongly recommend these ones: Geek Flare H3 Testing Tool and HTTP3Check.
Enable HTTP/3 For Your Site Whit Cloudflare
1. Log in your Cloudflare account then select the website/app you want to enable HTTP/3 on. Click on the “Network” button to continue.
2. Turn on the switch in the “HTTP/3 (with QUIC)” section.
Note that at this time, only a few new versions of the major browsers (Chrome, Safari, Firefox, Edge) support HTTP/3.
