1. 客户端取消
<html>
<head>
<meta http-equiv=”Expires” CONTENT=”0″>
<meta http-equiv=”Cache-Control” CONTENT=”no-cache”>
<meta http-equiv=”Pragma” CONTENT=”no-cache”>
</head>
2. 服务器端取消：
服务器端：
Response.Buffer = true;
Response.ExpiresAbsolute = DateTime.Now.AddDays(-1);
Response.Cache.SetExpires(DateTime.Now.AddDays(-1));
Response.Expires = 0;
Response.CacheControl = “no-cache”;
Response.Cache.SetNoStore();
3. Global里面：
protected void Application_BeginRequest(Object sender, EventArgs e)
{
HttpContext.Current.Response.Cache.SetNoStore();
}
<%@ OutPutCache Location=”None”%>
4. 页面基类：
public class PageBase : Page
{
public PageBase() {}
protected override OnLoad( EventArgs e ) {
Response.Cache.SetNoStore();
base.OnLoad();
}
}
