requestFacts

The request headers copied into a command's headers, beside the standard request facts the edge records: app_id, the application the caller resolver authenticated, and on the public port user_agent and remote_ip; none of the three can be listed, and each fact is cut to 512 characters. remote_ip is the server's remote address, which the host takes from the gateway's X-Forwarded-For (server.forward-headers-strategy is framework unless the application sets it, none included).
