    This feature may be used with `POST` requests to cache their responses. In such cases the
    request body is not used to determine the cache key, so you must manually add cache-relevant
    data to the override URL. For example, you could add a `request-body-sha256` query parameter so
    requests with the same POST data get the same cache entry.
