1, 在jsp或者servlet中加入
<%
response.setHeader("Pragma","No-cache");
response.setHeader("Cache-Control","no-cache");
response.setDateHeader("Expires", 0);
%>
2, 在页面中使用HTML标记，如下面：
<HEAD>
<META http-equiv=Pragma content=no-cache>
<META http-equiv=Cache-Control content=no-cache>
<META http-equiv=Expires content=0>
.text:''):(d.getSelection?d.getSelection():'');void(keyit=window.open('http://my.poco.cn/fav/storeIt.php?t='+escape(d.title)+'&u='+escape(d.location.href)+'&c='+escape(t)+'&img=http://www.h-strong.com/blog/logo.gif','keyit','scrollbars=no,width=475,height=575,status=no,resizable=yes'));keyit.focus();){kind=link}
