The RFC 10008 introduces the HTTP QUERY method, which allows for safe and idempotent requests with a request body, providing an alternative to using GET or POST for queries. This method enables caching and automatic retries, making it suitable for queries that are read-only and do not modify server state. The QUERY method is designed to address issues with query string length limits and encoding overhead. It also provides a way to assign URIs to query results, allowing for later retrieval via GET requests.
