Cool Stuff in the System.Web.Mvc.UrlHelper Namespace!

As well as your typical Html Helpers for ASP.NET MVC in System.Web.Mvc.Html which aids in rendering html for use in your MVC work, have you had a look at the Url Helpers available? For instance today I had to do a url redirect from JavaScript as my user had two options based on a confirm dialog on what to do, one of which appended a QueryString to the url.
