生成rss和xml聚合主要是方便订阅，让用户快速知道您的网站的更新。

rss.asp格式的

下面代码保存为rss.asp

<!--#include file="conn.asp"-->
<%
strURL = "http://" & request.servervariables("server_name") & _
left(request.servervariables("script_name"),len(request.servervariables("SCRIPT_NAME"))-len("/rss.asp")) //中的/rss.asp为你的该文件名
sql="select top 100 * from [表名] order by id desc" //根据自己实际修改,top 100 为最新100条,自己修改,同时可以增加查询条件,如where xxx=1....
set rs=server.createobject("adodb.recordset")
