HTTP QUERY Method Standardized: What It Means for Frontend Data Fetching

The new HTTP QUERY method, standardized in RFC 10008 (June 2026), combines safe/idempotent semantics of GET with the ability to send a request body like POST. This allows complex JSON queries without URL length limits, enabling caching and proxy optimizations for read-only requests. Developers can now use QUERY for search/filter endpoints instead of misusing POST.
