# urlHostAllowed

Returns the character set for characters allowed in a host URL subcomponent.

## Declaration

```swift
class var urlHostAllowed: CharacterSet { get }
```

## Discussion

Discussion The host component of a URL is usually the component immediately after the first two leading slashes. If the URL contains a username and password, the host component is the component after the @ sign. For example, in the URL http://username:password@www.example.com/index.html, the host component is www.example.com.
