Using UDP with the web on a wide scale will either replicate everything in TCP, inside UDP wrapping, or else cause big problems all over the Internet. It will be fast only in the beginning when a few clients are participating, but then screw over the infrastructure with degenerative congestive behaviors when "everyone" is on it.

networks - TCP and UDP basics: connecting to a website and UDP is best effort (ie no binding). UDP stands for User Datagram Protocol. You're right that it is best-effort, but that has nothing to do with ports. Both TCP and UDP use exactly the same IP addressing scheme, with the same 4-tuple. You'll probably never use it for HTTP … HTTP-over-QUIC to be renamed HTTP/3 | ZDNet Nov 12, 2018 User Datagram Protocol (UDP) - GeeksforGeeks

TCP Over HTTP Tunnel Free Server Provided by Fastssh.com Server: tcp.serverip.co Ports: 80, 8080, 3128 Password: fastssh.com Works only with fastssh.com SSH accounts. In some networks, the use of CONNECT method is blocked. In such cases, an HTTP tunnel can still be implemented using only the usual HTTP methods as POST, GET, PUT and DELETE. The server runs outside the blocked network … RDP over UDP failing on Windows 10 1809 with reduced MTU Since updating to Windows 10 build 1809 on both RDP client and server, I'm seeing a black screen after the initial logon sequence completes when connecting over a link with a smaller-than-ethernet MTU, and when UDP transport is enabled. These scenarios work as expected: LAN link, MTU 1500 bytes, both TCP and UDP transports enabled. TCP vs UDP - javatpoint

According to RFC, HTTP over UDP is not as valid as HTTP
