jsp不缓存
在有些应用中要求JSP不缓存数据，每次都从web服务器重新生执行（非内存中的数据）后生成的数据取出来显示在客户机上。这就要在JSP上强制不缓存，需要在JSP中加入以下代码
%@ page contentType="text/html;charset=gb2312" languang="java" buffer="none" %>
<META HTTP-EQUIV="pragma" CONTENT="no-cache">
<%
//设置缓存为空
response.setHeader("Pragma","No-cache");
response.setHeader("Cache-Control","no-cache");
response.setDateHeader("Expires", 0);
%>
<%
if(request.getProtocol().compareTo("HTTP/1.0")==0)
response.setHeader("Pragma","no-cache");
else if(request.getProtocol().compareTo("HTTP/1.1")==0)
response.setHeader("Cache-Control","no-cache");
response.setDateHeader("Expires",0);
%>
