Continuing to map request headers using their name in uppercase for the index, but we now map to an object with an unmodified name and value: { name: "", value: "" }. This prevents overwriting of the user's supplied headers, which many applications parse with case sensitivity, because we no longer use the modified, uppercase index when building the request.
