# HTTPURLResponse

```
class HTTPURLResponse
```

## Overview

The [`HTTPURLResponse`](/documentation/Foundation/HTTPURLResponse) class is a subclass of [`URLResponse`](/documentation/Foundation/URLResponse) that provides methods for accessing information specific to HTTP protocol responses. Whenever you make HTTP URL load requests, any response objects you get back from the [`URLSession`](/documentation/Foundation/URLSession), [`NSURLConnection`](/documentation/Foundation/NSURLConnection), or [`NSURLDownload`](/documentation/Foundation/NSURLDownload) class are instances of the [`HTTPURLResponse`](/documentation/Foundation/HTTPURLResponse) class.
