In simpler terms: **every request behaves like the first and only one**. --- ## What "stateless" means in plain words If an interaction is stateless: - the server **does not remember the client** - the server **does not remember past requests** - **all the necessary information must be in every request** The server processes the request, sends the response, and **forgets everything**. --- ## What this looks like in practice The client sends a request: > "Give me user 123's data, here is my token" The server: - checks the token - processes the request - sends the response - **does not store the client's state** The next request: > "Give me user 123's order list, here is my token" For the server, this is a **completely new request**, even if it came from the same client. --- ## A real-life example Stateless is like a line at an information desk: - you walk up - you ask a question - you get an answer - you walk away If you come back again, the clerk **is not obligated to remember** what you asked before. You have to **explain everything from scratch again**. --- ## Where statelessness shows up most often The best-known example is **HTTP**: - every HTTP request is independent - the server does not store session state by default - login, tokens, parameters, all of it is passed in the request Cookies, tokens, and sessions are **ways to work around statelessness**, not to eliminate it. --- ## Why statelessness is a good thing ### Advantages: - **simplicity** of server logic - **scalability** (any server can handle the request) - **reliability** (servers do not depend on state memory) - **convenient for distributed systems**For the reviewerNote to the moderator (optional)Visible only to the moderator.
