i solve this problem. At that tutorial, we have to change for different page.
//Append ID at the end of SEO Friendly URL
strTitle = "~/a/" + strTitle + "-" + t_id + ".aspx";
so at web config
<rewrite url="~/a/(.+)-(.+).aspx" to="~/Default.aspx?MyTitleId=$2"/>
suppose another page to another. at that page.
//Append ID at the end of SEO Friendly URL
strTitle = "~/b/" + strTitle + "-" + t_id + ".aspx";
so at web config
<rewrite url="~/b/(.+)-(.+).aspx" to="~/Default2.aspx?MyTitleId=$2"/>
