When I use Global.asax file for url rewriting purposes, I use Application_BeginRequest and follow up the code :

protected void Application_BeginRequest(object sender, EventArgs e)
       {
            //Get the current http context
             HttpContext InRequest = HttpContext.Current;

             //Get the current path
             string OldPath = InRequest.Request.Path.ToLower();

             //Check the path whether it is a contextual path
             if (InRequest.Request.RawUrl.Split('/').Length > 3)
             {
                 string Path = InRequest.Request.RawUrl.Split('/')[2];

                 Path = "/" + Path + "/";

                 string NewPath = "/abc/" + WebConfigurationManager.AppSettings[Path];

                 string ItemName = InRequest.Request.RawUrl.Split('/')[InRequest.Request.RawUrl.Split('/').Length - 1].Split('.')[0];

                 string ID = InRequest.Request.RawUrl.Split('/')[3];

                 //Rewrite the path with the actual path
                 InRequest.RewritePath(NewPath, "", "?id=" + ID, true);

             }
       }

However the Code is working fabulous but it dusturbs my website design when i run on local host, I think their is problem with iis can anyone help me?
