Realize the browser click the back button to refresh the interface

Need a browser background and refresh at work

在jsp中加入代码：<%
response.setHeader("Pragma","no-cache");   
response.setHeader("Cache-Control","no-cache");   
response.setDateHeader("Expires", 0);   
response.setHeader("Cache-Control", "no-store");

%>

There is no cache. Implement browser back and refresh.
