RFC 9110: HTTP semantics

RFC 9110 defines shared HTTP semantics, including methods, status codes, representation metadata and conditional requests. It is a reference for implementing predictable machine clients and interpreting server responses. Conditional request behavior is particularly relevant to clients that repeatedly check maintained information.
