With this StructureMap Registry you can inject static and global objects like HttpContext and Session into your MVC controllers and any other helper classes you may have. Taken from Matt Honeycutt's pluralsight course on Building your own Application Framework

MvcRegistry.cs

    public class MvcRegistry : Registry
    {
        public MvcRegistry() {
            For<BundleCollection>().Use(BundleTable.Bundles);
            For<RouteCollection>().Use(RouteTable.Routes);
            For<IIdentity>().Use(() => HttpContext.Current.User.Identity);
            For<HttpSessionStateBase>()
                .Use(() => new HttpSessionStateWrapper(HttpContext.Current.Session));
            For<HttpContextBase>()
                .Use(() => new HttpContextWrapper(HttpContext.Current));
            For<HttpServerUtilityBase>()
                .Use(() => new HttpServerUtilityWrapper(HttpContext.Current.Server));
        }
    }
