- @discussion Implementors of this protocol will receive messages indicating
- that a resource is about to be loaded, data has been received for a resource,
- an error has been received for a resource, and completion of a resource load.
- Implementors are also given the opportunity to mutate requests before they are sent.
- The various progress methods of this protocol all receive an identifier as the
- parameter. This identifier can be used to track messages associated with a single
- resource. For example, a single resource may generate multiple
- resource:willSendRequest:redirectResponse:fromDataSource: messages as it's URL is redirected.
