HTTP QUERY Method Arrives, But Caching Gets Tricky

The HTTP QUERY method (RFC 10008) is now official, offering a safe, idempotent, cacheable request with a body—solving the long-standing dilemma between GET and POST for complex reads. However, caching requires the request body to be part of the cache key, or else one client's response could be served to another. A new library, http-queryable, implements this correctly for Node.js frameworks.
