asp中如何在客户端把查询的结果集在本机上保存为excel

保存的代码：

'session( "sql ")= " "

================ 
session( "Sql ")保存的是查询的sql语句   
运行完后test.xls就保存在了服务器上了。但是我想保存在客户端上（在客户端上运行完后保存在了服务器上   服务器是运行iis这台机子）
客户端: 
查询页面:   <input   type=button   value= "导出 "   onClick= "javascript:export_onclick(); "> 
  function   export_onclick() 
{ 
window.location.href   =   "rp_export.asp?reports_sql= " sql;//这里的sql可以用你的session( "Sql ") 
} 
rp_export.asp: 
<%@   Language=VBScript%> 
<html> 
<head> 
<meta   http-equiv= "Content-Type "   content= "text/html;   charset=gb2312 "> 
<title> 无标题文档 </title> 
</head> 

<body> 
<% 
Response.Clear 
Response.ContentType   =   "text/xls " 
Response.AddHeader   "content-disposition ",   "attachment;   filename=export.xls " 

'点导出按钮后事件 

set   conn=server.createobject( "adodb.connection ") 
conn.open   "sql   server驱动 " 
SQL=session( "Sql ") 
'Set   rs=Server.CreateObject( "Adodb.RecordSet ") 
Set   rs=conn.execute(SQL) 
total=rs.fields.count 
while   not   rs.eof 
i=0 
while   i <cint(total) 
      Data=Data&rs(i)&chr(9) 
i=i 1     
wend 
Response.Write   Data&chr(13) 
Data= " " 
rs.moveNext 
wend 
rs.close 
conn.close   
Response.Flush 
Response.End
