IETF Publishes RFC 10008, Adding the QUERY Method for Safe Requests With a Body
HTTP has its first new standard method since PATCH in 2010. RFC 10008 defines QUERY, which lets you send a request body like POST but is safe, idempotent and cacheable like GET. That means no more URL-length hacks or POST-as-search for complex filters. Framework support is starting to land, but broad adoption will take a while.
