How can you prevent caching in JSP?
Execute the following scriptlet at the beginning of your JSP pages to prevent JSPs from being cached by browsers.You need both the statements to take care of some of the older browser versions.
<%
response.setHeader("Cache-Control","no-cache"); //HTTP 1.1
response.setHeader("Pragma","no-cache"); //HTTP 1.0
response.setDateHeader ("Expires", 0); //prevents caching at the proxy server
%>
If the above fails, try changing the first line to
response.setHeader("Cache-Control","no-store"); //HTTP 1.1
<%
response.setHeader("Cache-Control","no-cache"); //HTTP 1.1
response.setHeader("Pragma","no-cache"); //HTTP 1.0
response.setDateHeader ("Expires", 0); //prevents caching at the proxy server
%>
If the above fails, try changing the first line to
response.setHeader("Cache-Control","no-store"); //HTTP 1.1
