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

69 @discussion An implementor of WebResourceLoadDelegate should provide an identifier
70 that can be used to track the load of a single resource. This identifier will be
71 passed as the first argument for all of the other WebResourceLoadDelegate methods. The
72 identifier is useful to track changes to a resources request, which will be
73 provided by one or more calls to resource:willSendRequest:redirectResponse:fromDataSource:.
74 @result An identifier that will be passed back to the implementor for each callback.
75 The identifier will be retained.

125 @discussion In some rare cases, multiple responses may be received for a single load.
126 This occurs with multipart/x-mixed-replace, or "server push". In this case, the client
127 should assume that each new response resets progress so far for the resource back to 0,
128 and should check the new response for the expected content length.
