As promised, CloudFlare delivered HTTP/3 this week. If you don’t know what this is and what it could mean for web browsing in the future I highly recommend reading their blog and other sites about it. HTTP/3 brings another fundamental shift to transport protocols by building on the lessons learned from TCP and UDP. I’m particularly intrigued to see HTTP requests begin before the handshake is complete. CloudFlare released it to their customers who signed up to enable it early.
