asp 清除IE缓存的方法。
1、禁止客户端缓存要在<head>中加入类似如下内)：
复制代码 代码示例:
<META HTTP-EQUIV="pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache, must-revalidate">
<META HTTP-EQUIV="expires" CONTENT="Wed, 26 Feb 1997 08:21:57 GMT">
2、在服务器的动态网页中禁止缓存
1）、asp:
复制代码 代码示例:
<%
Response.Expires = -1
Response.ExpiresAbsolute = Now() - 1
Response.cachecontrol = "no-cache"
'-----------------或者
pStr = "private, no-cache, must-revalidate"
Response.ExpiresAbsolute = date()
Response.AddHeader "pragma", "no-cache"
Response.AddHeader "cache-control", pStr
%>
题外话，以下这个用于jsp页面中：
复制代码 代码示例:
response.setHeader("Pragma","No-cache");
response.setHeader("Cache-Control","no-cache");
response.setDateHeader("Expires", 0);
