I've created a simple url rewrite rule in UrlRewriting.config that take a fake url like

http://www.mysite.com/destination-guides/uk-scotland/england/

and turns it in to this one with an alternative templete

http://www.mysite.com/uk-scotland/england/?alttemplate=destinationguide

<add name="DestinationGuideRewrite" 
          virtualUrl="^~/destination-guides/(.*)/"
          rewriteUrlParameter="ExcludeFromClientQueryString"
          destinationUrl="~/$1?alttemplate=destinationguide"
                ignoreCase="true" />

Funtionally it working but rather than displaying the fake url http://www.mysite.com/destination-guides/uk-scotland/england/ in the browser's address bar it is showing the rewritten one, http://www.mysite.com/uk-scotland/england/?alttemplate=destinationguide which I don't want and according to my understanding it is not supposed to do.

I'm sure it used to work before and I'm not sure why it isn't now.

Any ideas of what to look at?
