Could you explain the concept of statelessness in RESTful architecture?

Statelessness in RESTful architecture means that each request from a client to a server must contain all the information necessary for its processing, and the server does not store information about the client's state between requests.

This simplifies scaling and increases reliability, as the server does not depend on previous interactions. For example, if a client sends a request with an authorization token, the server verifies it and responds without storing information about previous requests.

Thus, each request is independent and self-contained.
