禁止服务器端缓存：
Response.Expires = 0 或<meta http-equiv="Expires" CONTENT="0">
禁用客户端缓存。
HTML网页
<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">
ASP网页
<% Response.Expires = -1 Response.ExpiresAbsolute = Now() - 1 Response.cachecontrol = "no-cache" %>
PHP网页
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); header("Cache-Control: no-cache, must-revalidate"); header("Pragma: no-cache");
JSP
response.setHeader("Pragma","No-Cache"); response.setHeader("Cache-Control","No-Cache"); response.setDateHeader("Expires", 0);
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";
