IETF Standardizes HTTP QUERY Method for Read Requests with Bodies

The IETF published RFC 10008 defining the HTTP QUERY method, a new verb for read operations that require a request body. Unlike GET (no body semantics) or POST (not safe/idempotent), QUERY is safe, idempotent, and cacheable while carrying a payload. This fills a long-standing gap for complex search endpoints that need structured input without misusing HTTP methods.
