prevent JSP pages or servlets from being cached
September 21st, 2007
You can prevent the output from your dynamic JSP pages or servlets from being cached by browsers and proxy servers, simply by adding the following few lines of code at the beginning of your JSP page or servlet:
<%
response.setHeader("Cache-Control","no-cache");
response.setHeader("Pragma","no-cache");
response.setDateHeader("Expires", 0);
%>
