RFC 10008 defines a new HTTP method called QUERY, which sends query parameters in the request body instead of the URI while remaining safe and idempotent. It enables automatic retries, caching, and clearer intent compared to POST-based queries. The document specifies headers, media type requirements, status codes, and how servers assign URIs to queries and their results.

This article breaks down how to design a web system for scale, starting with scope, use cases, and constraints. It then walks through high-level and component design, scaling strategies (caching, load balancing, replication), performance tuning, reliability, and front-end considerations.

The author recounts the pitfalls of building a custom context layer—handling memory, data retrieval, caching and permissions—only to face endless complexity. They found that Redis Iris bundles syncing, search, semantic caching and memory into a single context engine that sits close to the agent runtime.
