I'm generating an html email in code that is to be sent to a recipient so they can click on a link and open up a certain .ascx control on my dnn 4 site passing in a querystring value.
Here's the relevant portion of my code,

"<a href=""" & "http://" & Request.ServerVariables("SERVER_NAME") & _
                                EditUrl("ID", intNewlyInsertedAuthID.ToString, "Sign") & _
                                """>Accept or Reject</a>

In my module definitions, I have an.ascx control that has a Key of "Sign" and Type of "Edit".

The link that gets sent in the email looks like this, 

http://localhost/DotNetNuke/DesktopModules/UtilityAuthorization/DotNetNuke/Default.aspx?tabid=53&ctl=Sign&mid=365&ID=76

which I realize has an extra DotNetNuke in it so I copy and paste into the browser like this,

http://localhost/DotNetNuke/DesktopModules/UtilityAuthorization/Default.aspx?tabid=53&ctl=Sign&mid=365&ID=76

but it gives me a 404 error and my Page_Load event of my "Sign" control never fires.

What am I doing wrong?
Thanks,
Greg
