### Downloading Information (Legacy)

[`WebDownload`](/documentation/WebKit/WebDownload)

`WebDownload` objects initiate download client requests on behalf of a delegate. A download request involves loading the data, decoding it (if necessary), and saving it to a file. Instances of this class behave similar to `NSURLDownload` except delegates of `WebDownload` may implement an additional delegate method. The method allows the delegate to specify the window to be used for authentication sheets. If the delegate does not implement this method, the `WebDownload` object will prompt the user for authentication using the standard WebKit authentication panel, as either a sheet or window. There are no additional methods defined in this class. See [`WebDownloadDelegate`](/documentation/WebKit/WebDownloadDelegate) for the delegate method.

[`WebDownloadDelegate`](/documentation/WebKit/WebDownloadDelegate)

The `WebDownloadDelegate` protocol declares one additional method for delegates of [`WebDownload`](/documentation/WebKit/WebDownload).
