Autofac returns different instance in asp.net mvc web api

I'm using autofac in an asp.net mvc and webapi project.

In the configuration I'm doing this :

var builder = new ContainerBuilder();
builder.Register(x => NHibernateConfigurator.BuildSessionFactory()).SingleInstance();
builder.Register(x => x.Resolve<ISessionFactory>().OpenSession()).InstancePerHttpRequest();
builder.RegisterSource(new AnyConcreteTypeNotAlreadyRegisteredSource());

builder.RegisterControllers(Assembly.GetExecutingAssembly());
builder.RegisterApiControllers(Assembly.GetExecutingAssembly());

var container = builder.Build();

DependencyResolver.SetResolver(new AutofacDependencyResolver(container));
config.DependencyResolver = new AutofacWebApiDependencyResolver(container);

Now the problem is that in an api controller if I inject ISession via the constructer and also call 

DependencyResolver.Current.GetService<ISession>()

it will return 2 different instances.

I'm guessing the problem is because of these 2 lines : 

DependencyResolver.SetResolver(new AutofacDependencyResolver(container));
config.DependencyResolver = new AutofacWebApiDependencyResolver(container);

But how can I make it return the same instance ?

Edit:

Just to be more clear - I'm expecting the same instance of ISession per HttpRequest. Right now I'm getting different instances on the same request.

Thanks

Ok, I think I found the answer - it can't be done .. at least not with DependencyResolver.

ASP .Net 4 Web Api RC + Autofac manual resolving

I did what it said in the comments, added IComponentContext to the constructor and used that to resolve what I needed.

It seems to be working. Thanks.
