What causes there to be no Cache-Control: no-cache header?

[claq2]

In a default WebAPI project, API controller response headers contain Cache-Control: no-cache. When I add an API controller to the MVC 5 Boilerplate template project there is no such response header. What bit of code or config is preventing this?

Specifically, my Startup.ConfigureContainer has the following:

var httpConfig = new HttpConfiguration();
httpConfig.MapHttpAttributeRoutes();
httpConfig.Routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { id = RouteParameter.Optional }
);

IContainer container = CreateContainer();
app.UseAutofacMiddleware(container);

// Register MVC Types 
app.UseAutofacMvc();

httpConfig.DependencyResolver = new AutofacWebApiDependencyResolver(container);
app.UseWebApi(httpConfig);

And I'm comparing this setup against the VS 2015 template when selecting an API project.

Web API 2 and MVC 5 are different frameworks. The boilerplate MVC 5 template is not intended to be used for building API's.
