| +// The BackoffManager class is used to implement exponential back-off for
|
| +// network requests in case of sever errors. Users report to the BackoffManager
|
| +// class when they make a request to or receive a response from a given url. The
|
| +// BackoffManager class provides the earliest time at which subsequent requests
|
| +// should be made.
