# URLSession.ResponseDisposition

Constants indicating how a data or upload session should proceed after receiving the initial headers.

```
enum ResponseDisposition
```

## Overview

When a data or upload task first receives a response, it calls the  [`urlSession(_:dataTask:didReceive:completionHandler:)`](/documentation/Foundation/URLSessionDataDelegate/urlSession(_:dataTask:didReceive:completionHandler:)) method of [`URLSessionDataDelegate`](/documentation/Foundation/URLSessionDataDelegate). Implement this method to inspect the received [`URLResponse`](/documentation/Foundation/URLResponse) and then call the provided completion handler. The first parameter to the completion handler is of this type, a disposition that tells the task how to proceed.
