我认为在ASP中最好的办法是用编程实现定时刷新Cache，也就是说给Application中储存的设一个过期时间。当然，在ASP中Application对象没有这样一个ExpireTime属性。这需要用程序实现。
Code
ASP：default.asp
<%@Language=VBScript%>
<%Option Explicit%>
<%Response.Buffer=True%>
<!--#include file = "conn.asp"-->
<!--#include file = "GetCache.asp"-->
<HTML>
<HEAD>
<TITLE>ASP Cache演示</TITLE>
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=gb2312">
</HEAD>
<BODY>
<h4>每隔10秒刷新Cache：</h4>
<%
response.Flush
GetHTMLStream
response.Write
HTMLStream
%>
</body>
</html>
<%
Const CACHE_DEFAULT_INTERVAL = 30 '每隔30秒刷新一次cache
Dim HTMLStream
Dim IsExpires
IsExpires = CacheExpires
Function CacheExpires
Dim strLastUpdate
Dim result strLastUpdate = Application("LastUpdate")
If (strLastUpdate = "") Or (CACHE_DEFAULT_INTERVAL < DateDiff("s", strLastUpdate, Now)) Then
result = true
SetLastUpdateTime
Else
result = false
End If
CacheExpires = result
End Function
%>
