routes - How to leave URL parameters unescaped in ASP.NET MVC?

Question

I've noticed the returnurl URL parameter on the Stackoverflow login/logout links are not escaped but when I try to add path as a parameter to a route it gets escaped.

So /login?returnurl=/questions/ask shows /login?returnurl=%2fquestions%2fask and it's kind of ugly. How do I get it to not escape the returnurl value?

Here's what I'm doing in the code:

Html.ActionLink("Login", "Login", "Account", new { returnurl=Request.Path }, null)

How do I get it to not escape the returnurl value

How's about this?

var url = Url.Action("Login", "Account", new {returnurl = Request.Path});
var unEncodedUrl = HttpUtility.UrlDecode(url);
Response.Write("<a href='" + unEncodedUrl + "'>...</a>");

Be sure that's what you want though, URL encoding has its purpose.
