奇怪的cookies丢失问题
网站：http://sh.ailv.cn
在向购物车增加第12个商品时，三个商品的cookies数据丢失，以后每向购物车增加一个商品，就丢失一个，一直保留8个商品cookies。太奇怪了。
代码如下：
<!--#include file= "conn.asp "-->
<html>
<head>
<meta http-equiv= "Content-Type " content= "text/html; charset=gb2312 ">
<title> 购物车 </title>
<link href= "css/css.css " rel= "stylesheet " type= "text/css " />
<style type= "text/css ">
<!--
body {
background-color: #F5E9ED;
}
-->
</style> </head>
<body>
<table width= "563 " height= "174 " border= "0 " cellpadding= "0 " cellspacing= "8 " bgcolor= "FFDEEA ">
<tr>
<td valign= "top " bgcolor= "#FFFFFF ">
<%
if request.QueryString( "action ")= "reset " then
idlist=request.Cookies( "idlist ")
idlist1=request.Form( "id ")
id=split(idlist, ", ")
id1=split(idlist1, ", ")
'删除选购商品
for i=0 to ubound(id)
if len(id(i))> 0 then
del=true
for j=0 to ubound(id1)
if clng(id1(j))=clng(id(i)) then
del=false
exit for
end if
next
if del then
response.Cookies( "pro "&id(i)).expires= "1/1/1998 "
end if
end if
next
'修改选购商品定购件数
dim errmsg,cnum
for j=0 to ubound(id1)
keyname=clng(id1(j))
cnum=clng(request.Form( "m_ "&keyname))
if cnum=0 then
errmsg= "修改数量失败，订单商品数量为0！ "
else
response.Cookies( "pro "&keyname)( "num ")=cnum
end if
next
response.Cookies( "idlist ")=idlist1& ", "
if len(errmsg)> 0 then
response.Write( " <script language=javascript> alert( ' "&errmsg& " ');location.href= 'buy.asp '; </script> ")
response.End()
else
response.Redirect( "buy.asp ")
end if
elseif request.QueryString( "action ")= "clear " then
idlist=request.Cookies( "idlist ")
id=split(idlist, ", ")
for i=0 to ubound(id)
if len(trim(id(i)))> 0 then
keyname= "pro "&clng(id(i))
response.Cookies(keyname).expires= "1/1/1998 "
end if
next
response.Cookies( "idlist ")= " "
response.Redirect( "buy.asp ")
elseif request.QueryString( "id ") <> " " then
proid=clng(request.QueryString( "id "))
set rs=server.CreateObject( "adodb.recordset ")
rs.open "select * from v_uid_pro where uid= "&request.Cookies( "uid ")& " and isview=1 and id= " & proid,conn,1,1
idlist=request.Cookies( "idlist ")
id=split(idlist, ", ")
