Why LLMs Are Undermining 20‑Year‑Old Stateless Web Architecture

The article explains how the longstanding web architecture that separates stateful databases from stateless compute is being challenged by large language models and AI agents, which introduce long‑running, stateful, bidirectional workflows, exposing the need for new routing primitives such as persistent pub/sub channels rather than traditional HTTP‑load‑balancer setups.

Why JWT Still Needs Redis Despite Its Stateless Promise

Although JWT is marketed as a stateless, database‑free authentication method, real‑world applications often store token identifiers in Redis to handle logout, password changes, and token renewal, which reintroduces state and a database lookup.

Why Most Projects Choose Token + Redis Over Stateless JWT

Although JWT is marketed as a decentralized, stateless solution, the majority of real‑world applications still rely on a Token + Redis approach because it simplifies logout handling, avoids Redis outages, and aligns better with practical security requirements.

JWT Explained: When to Use Stateless Tokens and What to Watch Out For

JSON Web Tokens (JWT) provide a compact, signed, self-contained way to authenticate API requests without server-side session storage, offering scalability and speed, while introducing trade-offs such as revocation challenges, token size, and exposure of unencrypted payloads, making them ideal for distributed systems but unsuitable for scenarios requiring immediate logout or sensitive data.

Understanding REST Architecture and Its Constraints

REST, an architectural style defined by Roy Fielding, structures web APIs around resources identified by URIs, exchanged as representations, and manipulated through stateless, uniform HTTP methods that enforce constraints such as client‑server separation, caching, layered systems, and optional code‑on‑demand to ensure scalable, predictable interactions.
