Put a coordinate in the fragment — #30.2460563,-97.786499 — and this page computes its cells in your browser and reads the world's release record. The coordinate never leaves the browser, so it reaches no log and no cache key.
#30.2460563,-97.786499
This page computes the containing S2 cells for the coordinate in its URL and reads the world's release record, both in the browser and with no script running on any server. With scripting off it computes nothing; the release record itself is worlds/main/current.json, on this same origin.
