禁用客户端缓存
HTML
          <META   HTTP-EQUIV="expires"   CONTENT="0">

         <META   HTTP-EQUIV="pragma"   CONTENT="no-cache">
          <META   HTTP-EQUIV="Cache-Control"   CONTENT="no-cache,   must-revalidate">

ASP
<%
          Response.Expires   =   -1
          Response.ExpiresAbsolute   =   Now()   -   1
          Response.cachecontrol   =   "no-cache"
%>
PHP
          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";

要强制进行http请求其实很简单.就象csdn现在这样,在后面缀一个随机参数(该参数应该以当前时间为种子).那么无论什么类型的文件,都会重新发起http请求

<%@ OutputCache Location="None" VaryByParam="None" %>
和
Response.Buffer   =   true;
Response.ExpiresAbsolute   =   DateTime.Now.AddDays(-1);
Response.Expires   =   0;
Response.CacheControl   =   "no-cache";
