问题
When you use ASP.NET forms authentication, and you want to surf to a secure page like securepage.aspx, you would be redirected to this URL:
http://www.example.com/login.aspx?returnurl=securepage.aspx`
Is there a way to get the absolute URL in login page, like:
http://www.example.com/login.aspx?returnurl=http://www.example.com/securepage.aspx
I need this feature, because I'm working on a rather complicated SSO project, and I need to always work with absolute URLs.

try this
<httpRuntime useFullyQualifiedRedirectUrl=”true”
