request headers. This works fine if the request is initiated from a browser either directly or via XHR/Fetch, but I need a way to hit this worker API with a backend HTTP request and "inform" Cloudflare of what IP address should be used to determine the values for the geo-headers.X-Forwarded-For and CF-Connecting-IP headers in my request. The former doesn't do anything, and the latter throws a 403 Forbidden status.
