C#中禁止cache的方法！
Response.Buffer=true;
Response.ExpiresAbsolute=System.DateTime.Now.AddSeconds(-1);
Response.Expires=0;
Response.CacheControl="no-cache";

将网页设置成不在客户端缓存:
<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">

but it is unsafe!
Second:
you can keep the cache empty
