Close multi opener, parent of a web window and redirect to default home page

assume default home page is default.aspx, default first page is default.htm.

default.htm:

<script type="text/javascript" language="javascript">
        <!--            
            setTimeout('OpenWin()', 100);
            
            function OpenWin()
            ...{
                if(window.parent != null && window.opener == null)
                ...{
                    window.parent.location = "Default.aspx";
                }
                else if(window.opener != null && !window.opener.closed)
                ...{
                    window.opener.location = "default.htm"; // recursion to close opener's opener's opener...
                    window.close();
                }
                else
                ...{
                    window.location = "Default.aspx";
                }
            }
        //-->
    </script>

 

code to redirect to default.htm:

private void ResponseRidirect()
        ...{
            string currentUrl = this.Request.Url.ToString();
            string appPath = this.Request.ApplicationPath;
            int index = currentUrl.IndexOf(appPath);
            string destUrl = string.Format("{0}/default.htm", currentUrl.Substring(0, index + appPath.Length));

            string script = "<script language="javascript" type="text/javascript"> " +
                "window.location = "" + destUrl + ""; " +
                "</script>";
            Response.Write(script);
            Response.End();
