Protocols for Modern Web Communication
Protocols for Modern Web Communication Web applications use a stack of protocols to move data between clients and servers. At the base are transport rules, which decide how packets travel. On top, security protects privacy. Above that, application protocols define how services talk to each other. Knowing these layers helps developers build faster, safer sites and clearer APIs. Transport protocols HTTP/1.1, HTTP/2, and HTTP/3 are the main options today. HTTP/3 runs over QUIC, a modern transport that reduces latency and improves multiplexing. HTTP/2 adds binary framing and header compression, which cuts some round trips. HTTP/3 aims to keep connections lighter and faster, even on imperfect networks. In practice, many sites still support HTTP/1.1 for compatibility, but upgrading to HTTP/3 can bring noticeable gains. ...
