Cache Key Builder

Create a collision-safe JSON key template preserving duplicate query pairs and stable same-name order. Header/cookie inputs are names, not supplied values: this template cannot safely partition real personalized responses until actual values and cache rules are added. Method/host/path remain distinct components; no cache is modified.
