And if you would like to send the **Cookies** with the WebSocket connection request to the server, you should set any cookie using the `WebSocket.SetCookie (WebSocketSharp.Net.Cookie)` method before connecting, like the following.
```cs
ws.SetCookie (new Cookie ("nobita", "gunfighter"));
ws.SetCookie (new Cookie ("name", "nobita"));
```
As a **WebSocket Server**, if you would like to check the Origin header and Cookies included in each WebSocket connection request, you should set each validation for the Origin header and Cookies in your `WebSocketService`, for example, using the `AddWebSocketService<T> (string, Func<T>)` method with initializing, like the following.
