ASP.NET Path Problem IIS vs Visual Studio

[xeroxero]

With this code, the built-in "Cassini" web server from Visual Studio
..NET 2005 (SP1) prepends "https", but on IIS 6, it prepends "http".

Why?


bool sslIsEnabled =
HttpContext.Current.Request.ServerVariables["HTTPS"] != "off";
appPath = ( sslIsEnabled ? "http://" : "https://" ) +
HttpContext.Current.Request.ServerVariables["SERVER_NAME"].ToString()
+ hostPort + appPath;
