# webView(_:resource:didReceive:from:)

Invoked after a resource has been loaded.

## Declaration

```swift
optional func webView(_ sender: WebView!, resource identifier: Any!, didReceive response: URLResponse!, from dataSource: WebDataSource!)
```

## Parameters

- `sender`: The web view that sent this message.
- `identifier`: An identifier object used to track the resource being loaded by dataSource.
- `response`: The reply that was received.
- `dataSource`: The data source for this web view.

## Discussion

Discussion In some rare cases, multiple responses may be received for a single resource. This happens in the case of multipart/x-mixed-replace, also known as a server push. In this case, delegates should assume that the progress of loading this resource restarts, and the expected content length may change.
