# URLSession.ResponseDisposition.becomeStream

Convert the response for this request to use a URLSessionStreamTask.

## Declaration

```swift
case becomeStream
```

## Discussion

Discussion When used with the completion handler from urlSession(_:dataTask:didReceive:completionHandler:), this disposition converts the task to a stream task. This will result in your delegate’s urlSession(_:dataTask:didBecome:) being called to provide you with the new stream task that supersedes the current task.
