Hi, I'd like to accomplish the following:

class SearchController : AsyncController
{
    public ActionResult Index(string query)
    {
        if(!isCached(query))
        {
            // here I want to asynchronously invoke the Search action
        }
        else
        {
            ViewData["results"] = Cache.Get("results");
        }

        return View();
    }

    public void SearchAsync()
    {
        // some work

        Cache.Add("results", result);
    }
}

I'm planning to make an AJAX 'ping' from the client in order to know when the results are available, and then display them.

But I don't know how to invoke the asynchronous Action in an asynchronous way!

Thank you very much. Luis
