title: How do you get access to the current System.Web.Routing.RequestContext from within a custom helper method in ASP.NET MVC?
body: <p>I'm writing a helper method for ASP.NET MVC and I need to call <code>Url.Content</code> to get an appropriate URL for the context.  However, in order to create a new <code>UrlHelper()</code> I need to get the current <code>RequestContext</code> (<code>System.Web.Routing.RequestContext</code> to be precise) and I'm not sure how to grab it. Anyone know?</p>
