How to remove OutputCache on ChildAction?

Question

I am trying to take advantage of the donut caching features in .Net MVC 3. For my Home page, in my home controller, I have:

public ActionResult Index()
{
    return View();
}

[ChildActionOnly]
[OutputCache(Duration=3600)]
public ActionResult IndexMain()
{
    return PartialView(ViewModelRepository.GetIndexViewModel());
}

I my view, I have:

<% Html.RenderAction("IndexMain");%>

This all works fine. However, when the data changes, I run:

var urlToRemove = Url.Action("IndexMain", "Home");
Response.RemoveOutputCacheItem(urlToRemove);

The RemoveOutputCacheItem executes without an error, but the ChildAction cache is not invalidated. Is there a way to programmatically remove a cache item from a ChildAction?

Have you tried using the VaryBy properties such as VaryByParam or VaryByCustom

Looks like this is the only way to go without using a full-blown reimplementation. – marapet Mar 26 '13 at 14:52
