* - redirect_url (string|null) - the resolved location of redirect responses, null otherwise
* - response_headers (array) - an array modelled after the special $http_response_header variable
* - start_time (float) - the time when the request was sent or 0.0 when it's pending

* - user_data (mixed) - the value of the "user_data" request option, null if not set
