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。
HTM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;
