WCF - 将cookie传递给netHttpBinding（WebSocket）通信

Question

我需要在初始化netHttpBinding（WebSocket）通信时从客户端向服务器发送一些cookie。

如果是基于HTTP的通信，我通过实施IClientMessageInspector并在Message方法中添加HttpRequestMessageProperty属性BeforeSendRequest来实现相同的目标：

    public object BeforeSendRequest(ref Message request, IClientChannel channel)
    {
        var properties = request.Properties;
        var propertyName = HttpRequestMessageProperty.Name;
        var httpProperty = properties.ContainsKey(propertyName)
            ? (HttpRequestMessageProperty)properties[propertyName]
            : new HttpRequestMessageProperty();

        httpProperty.Headers[HttpRequestHeader.Cookie] = cookie.ToString();

        properties[propertyName] = httpProperty;

        return null;
    }

但是当我使用WebSockets时，我不知道如何实现相同的目标。
