I have NHibernate hooked up in my asp.net mvc app.

Everything works fine, if I DON'T dispose the ISession. I have read however that you should dispose, but when I do, I get random "Session is closed" exceptions.

I am injecting the ISession into my other objects with Windsor.

Here is my current NHModule:

public class NHibernateHttpModule : IHttpModule
{
    public void Init(HttpApplication context)
    {
        context.BeginRequest += context_BeginRequest;
        context.EndRequest += context_EndRequest;
    }

    static void context_EndRequest(object sender, EventArgs e)
    {
        CurrentSessionContext.Unbind(MvcApplication.SessionFactory);
    }

    static void context_BeginRequest(object sender, EventArgs e)
    {
        CurrentSessionContext.Bind(MvcApplication.SessionFactory.OpenSession());
    }

    public void Dispose()
    {
        // do nothing
    }
}

Registering the ISession:

container
  .Register(Component.For<ISession>()
     .UsingFactoryMethod(() =>  MvcApplication.SessionFactory.GetCurrentSession()).LifeStyle.Transient);

The error happens when I tack the Dispose on the unbind in the module. Since I keep getting the session is closed error I assume this is not the correct way to do this, so what is the correct way?

Thanks, Joe
