Navigate to a normalized url



Hi all, I have an embed webbrowser and making it navigate to an url but
when I try to navigate to an url like this one :
'www.somenonexistantdomain42.com' the event NAVIGATEERROR as well as
DISPID_DOCUMENTCOMPLETE are neither fired...

Navigating to http://www.somenonexistantdomain42.com let me have a
normal error DNS error page as the page is not find. So I thing the
problem come from the normalization of url...

How to force the normalization of the url ?
