For anyone still wondering, a more complete answer is available at http://devio.wordpress.com/2009/10/19/get-absolut-url-of-asp-net-application/.

public string FullyQualifiedApplicationPath
{
    get
    {
        //Return variable declaration
        var appPath = string.Empty;

        //Getting the current context of HTTP request
        var context = HttpContext.Current;

        //Checking the current context content
        if (context != null)
        {
            //Formatting the fully qualified website url/name
            appPath = string.Format("{0}://{1}{2}{3}",
                                    context.Request.Url.Scheme,
                                    context.Request.Url.Host,
                                    context.Request.Url.Port == 80
                                        ? string.Empty
                                        : ":" + context.Request.Url.Port,
                                    context.Request.ApplicationPath);
        }

        if (!appPath.EndsWith("/"))
            appPath += "/";

        return appPath;
    }
}
