如何通过ASP.NET重定向和修改无扩展名的URL？

<system.webServer>
 <rewrite>
   <rules>
      <rule name="Remove Querystring" stopProcessing="true">
       <match url=".*?" />
       <conditions>
          <add input="{QUERY_STRING}" pattern="^[\&amp;|\?|\=|\=|\!]+$" negate="true" />
        </conditions>
       <action type="Redirect" url="{R:1}" redirectType="Permanent" appendQueryString="true" />
      </rule>
    </rules>
  </rewrite>
</system.webServer>

<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
  Response.Redirect(Request.Url.ToString(), false);
}
</script>
