REST (Representational State Transfer) is an architectural style for distributed hypermedia systems, first introduced in Roy Fielding’s 2000 doctoral dissertation “Architectural Styles and the Design of Network-based Software Architectures” at UC Irvine. Fielding, one of the principal authors of the HTTP protocol, analyzed the success factors of the web and systematized them into architectural principles. Since then, REST has become the de facto standard for modern web API design and is widely used across distributed systems, including microservice architectures, mobile applications, and Single Page Applications (SPAs). ...

HTTP (HyperText Transfer Protocol) methods define how clients and servers communicate on the web. HTTP/1.1 (RFC 7231) defines 9 standard methods: GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS, CONNECT, and TRACE. Each method has important properties such as safety and idempotency, which shape caching, retry behavior, RESTful API design, and web application development. History and Evolution of HTTP Methods What is HTTP (HyperText Transfer Protocol)? An application layer protocol for transferring hypertext documents between clients and servers on the web. It operates on a request-response model where the method used in each request defines the semantics of the operation to be performed. ...
