'设置缓存
Function SetCache(xmlFilePath,CacheTime,Conn,Sql)
set cache=new XmlCacheCls
Set cache.Conn=Conn
cache.XmlFile=xmlFilePath
cache.Sql=Sql
cache.CacheTime=CacheTime
cache.WriteDataToXml
Set cache = Nothing
End Function
'读取缓存
Function ReadCache(xmlFilePath,Conn,Sql,ByRef ReadOn)
set cache=new XmlCacheCls
Set cache.Conn=conn
cache.XmlFile=xmlFilePath
cache.Sql=Sql
cache.ReadData
ReadCache=cache.SQLArr
ReadOn=cache.ReadOn
End Function
%>

使用方法:
1 缓存数据到xml
代码:
复制代码 代码如下:

<!--#include file="Conn.asp"-->
<!--#include file="Xml.asp"-->
<%
set cache=new XmlCacheCls
Set cache.Conn=conn
cache.XmlFile=Server.Mappath("xmlcache/index/Top.xml")
cache.Sql="select top 15 prod_id,prod_name,prod_uptime from tblProduction"
cache.WriteDataToXml
%>

2 读取缓存数据
代码:
复制代码 代码如下:

<!--#include file="Conn.asp"-->
<!--#include file="Xml.asp"-->
<%
set cache=new XmlCacheCls
Set cache.Conn=conn
cache.XmlFile=Server.Mappath("xmlcache/index/Top.xml")
cache.Sql="select top 15 prod_id,prod_name,prod_uptime from tblProduction order by prod_id asc"
cache.ReadData
rsArray=cache.SQLArr
if isArray(rsArray) then
for i=0 to ubound(rsArray,2)
for j=0 to ubound(rsArray,1)
response.Write(rsArray(j,i)&"<br><br>")
next
next
end if
%>
缓存时间,单位秒 默认10分钟;也可以自己设定 cache.CacheTime=60*30 30分钟
