How does Castle Windsor respond to a class which implements multiple interfaces?

Question

For example I have two interfaces: ICustomerService and IOrderService which each has a couple of functions like GetCustomer, GetOrder, etc.

I want one class to implement both interfaces: Server.

How does Castle Windsor respond to this? Is it possible in the first place? When I resolve the Server object based on one of the two interfaces, will I get the same object? What happens when I have a constructor that has both interfaces in its parameters? Will there still be one object constructed.

assuming the LifeStyle is left to its default: Singleton.

I keep a solution on my system with NUnit and Windsor configured, so I can easily answer questions like yours. Quick test:

[Test]
public void CheckSingleton()
{
 var container = new WindsorContainer();
 container.AddComponentWithLifestyle("service.SomeService", typeof(ISomeService), typeof(ConcreteType), LifestyleType.Singleton);
 container.AddComponentWithLifestyle("service.AnotherService", typeof(IAnotherService), typeof(ConcreteType), LifestyleType.Singleton);

 var someService = container.Resolve<ISomeService>();
 var anotherService = container.Resolve<IAnotherService>();

 Assert.AreSame(someService, anotherService);
}

=> FAILED

therefore: Sorry, it seems like there is a singleton per service registration.
