# webView(_:didStartProvisionalLoadFor:)

Called when a page load is in progress in a given frame.

## Declaration

```swift
optional func webView(_ sender: WebView!, didStartProvisionalLoadFor frame: WebFrame!)
```

## Parameters

- `sender`: The web view containing the frame.
- `frame`: The frame being loaded.

## Discussion

Discussion This method is invoked when a new client request is made by sender to load a provisional data source for frame. This method may be invoked after sending load(_:) to a WebFrame object or as a consequence of the user clicking a link displayed in a web frame view. Delegates might implement this method to notify the user that a request is in progress. Additional information about the request can be obtained from the data source of frame.
