Why It Matters

For platform engineers building search or data APIs, QUERY promises cacheable reads without URL bloat, but nginx's caching gap means you'll need custom middleware or a different proxy until support lands.

Key Takeaways

Evaluate your proxy layer (nginx, Envoy, etc.) for QUERY method support before adopting RFC 10008 in production—caching is the primary advantage, not just method semantics.

nginx will proxy the new HTTP QUERY method. It will never cache one.

Summary

The IETF's RFC 10008 defines the HTTP QUERY method—a safe, idempotent, cacheable alternative to POST for read operations with complex parameters. Testing eight language models to generate clients for a QUERY-only API revealed all models correctly used the method when explicitly prompted, but defaulted to POST without guidance. The real failure point was nginx, which proxies QUERY requests but refuses to cache them, undermining the method's key benefit.
