Check if a website supports HTTP/2
HTTP/2 is like the next generation of web communications, offering features that put the old HTTP/1.1 to shame. One of the brightest new features is multiplexing. Unlike previous versions that could only send one request at a time (think slow single-file queues in supermarkets), HTTP/2 can send multiple requests over a single connection (multiple Imagine a highly efficient supermarket with checkout). . . This means that different parts of a web page can load at the same time, making the entire page load much faster.
