        if (!isredirected && !isredirected2 && !isredirected3 && !isredirected4 && !isredirected5 && !isredirected6)
        {
            HttpContext obj = HttpContext.Current;
            string finalurl = curruntpath + ".aspx";
            if (System.IO.File.Exists(Server.MapPath(finalurl)))
            {
                obj.RewritePath(finalurl);
            }
