Detect session expiration inside asp.net mvc action method

Question

I want to detect session timeout inside mvc action method. I know that I can use Authorize attribute to detect it. But I don't want to use it at this moment.

public async Task<ActionResult> Check()
{
    return View();
}

Is there any way to achive this kind of thing?

Answer 1

It seems there are now ActionFilter for async MVC methods: Async action filter in MVC 4

Try to authorize inside the action or call a authorize method inside async actions.
