private void SetPageNoCache()
{
Response.Buffer = true;
Response.ExpiresAbsolute = System.DateTime.Now.AddSeconds(-1);
Response.Expires = 0;
Response.CacheControl = "no-cache";
Response.AppendHeader("Pragma", "No-Cache");
}
1。 取消快取
（2）客戶端取消
<html>
<head>
<meta http-equiv="Expires" CONTENT="0">
<meta http-equiv="Cache-Control" CONTENT="no-cache">
<meta http-equiv="Pragma" CONTENT="no-cache">
</head>
（3）伺服器具端取消：
伺服器端：
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();
Global裡面：
protected void Application_BeginRequest(Object sender, EventArgs e)
{
HttpContext.Current.Response.Cache.SetNoStore();
}
<%@ OutPutCache Location="None"%>
頁面基類：
public class PageBase : Page
{
public PageBase() {}
protected override OnLoad( EventArgs e ) {
Response.Cache.SetNoStore();
base.OnLoad();
}
}
最簡單的辦法 :-)
學CSDN的這個論壇，在URL後面隨機的加一些沒用的引數，比如：
http://xxx/xxx/xxx.jpg?p=xxx
IE是用過URL來控制快取的，這樣就解決了
