Verify HTTP/2 & HTTP/3 Support

HTTP/2 (Hypertext Transfer Protocol version 2) is a major revision of the HTTP protocol, which is the foundation of data communication on the World Wide Web. It was developed as an improvement over the previous HTTP/1.1 version to enhance web performance and efficiency. HTTP/3 goes a step further and runs over QUIC instead of TCP, for faster connections and better performance on unreliable networks.
