Overview

Plain Rack middleware implementing the Inertia protocol's asset versioning handshake: on a GET Inertia request whose X-Inertia-Version header doesn't match the server's configured version, respond with a 409 + X-Inertia-Location (empty body) instead of calling downstream, so the client performs a full browser visit and picks up new assets.
