web.config 能否配置二级域名？

Question

一个域名下后跟不同demo名不行吗
  <rewriter>
    <rewrite url="~/demo-(.+)" to="~/Content.aspx?id=$1" />
  </rewriter>在content.aspx里根据id选择跳转到指定目录/页面(配置文件里还要设置demo对应真实目录)string url=System.Configuration.ConfigurationManager.AppSettings[Request.QueryString["id"]];
Response.Redirect(url);  <appSettings>
    <add key="news" value="demo1" />
    <add key="bbs" value="demo2" />
    <add key="blog" value="demo3"/>
  </appSettings>
