# domain

The domain of the cookie.

## Declaration

```swift
var domain: String { get }
```

## Discussion

Discussion If the domain does not start with a dot, then the cookie is only sent to the exact host specified by the domain. If the domain does start with a dot, then the cookie is sent to other hosts in that domain as well, subject to certain restrictions. See RFC 6265 for more detail.
