HTTP/3 is coming - what's new in it?

HTTP/3 is a modern data transmission protocol that promises significant performance improvements over its predecessors, HTTP/1.1 and HTTP/2. The main difference lies in the fact that HTTP/3 uses QUIC as its transport protocol instead of TCP, which is utilized by older versions. QUIC combines features of both TCP and UDP, enabling faster connection establishment and better management of packet loss. This makes the protocol particularly effective for applications where speed is crucial, such as video streaming and online gaming. The article also discusses how HTTP/3 performs in real-world conditions, highlighting its benefits as well as the challenges that may arise during implementation. In particular, it points out issues related to compatibility and support from existing servers and browsers, alongside the gradual adoption of this protocol across different parts of the Internet.
