Top 9 Improvements that Make HTTP/2 Better
HTTP/2 was designed for better end-user experience by making it is faster and more secure.
HTTP/2 reduces latency by enabling request and response multiplexing, minimizing protocol overhead via compressing header fields, and adding support for request prioritization and server push. Also, security is better with the addition of TLS with minimum key size requirements. A major goal of HTTP/2 was to maintain high-level compatibility with HTTP/1.1. Most of the high-level syntax of HTTP is preserved, such as methods, status codes, and header fields. HTTP/2 does not obsolete HTTP/1.1 because the two protocols share the same message syntax, URI schemes and default port numbers you can use HTTP/1.1 or HTTP/2 over the same default port.
