 // It analyzes requests of a specific URL over some period of time, in order to
 // deduce the back-off time for every request.
 // The back-off algorithm consists of two parts. Firstly, exponential back-off
 // is used when receiving 5XX server errors or malformed response bodies.
 // The exponential back-off rule is enforced by URLRequestHttpJob. Any
 // request sent during the back-off period will be cancelled.
 // Secondly, a sliding window is used to count recent requests to a given
 // destination and provide guidance (to the application level only) on whether
 // too many requests have been sent and when a good time to send the next one
 // would be. This is never used to deny requests at the network level.
