Using MVC-style urls in the Form-based login process

The forms-based login process uses standard ASP.NET forms authentication, in which ASP.NET automatically redirects you to the login page whenever a 401 status is set in the response. When it does so, it adds a ReturnUrl querystring parameter to the Url to the login page, so that this page can redirect back to it when logging it is successful.

/Login?ReturnUrl=http:%2f%2fyourdomain.com%2fPub%2fHome%2fMeta-Navigaton%2fiXperion-Status-Info.html

By setting the login item to use Url Parameters, this passing of querystring parameters can be avoided and replaced with MVC-style URL parameters:

/Login.mvc/ReturnTo/http$3A$2F$2Fhawking$2FPub$2FHome$2FiXperion$252DStatus$252DInfo.html

The result is a Web Guidelines compliant url.
