Redirect to login page when user clicks on back button after logout in JSF [duplicate] - jsf

Question

This question already has answers here:
Avoid back button on JSF web application
(2 answers)
Closed 6 years ago.
When the user clicks on the logout page it takes him to the login.xhtml.Now when the user clicks the back button it is taking him to the page before logout and I am trying to avoid this by using the doFilter which has been mentioned in many posts and my code is:
HttpServletRequest request = (HttpServletRequest) req;
HttpServletResponse response = (HttpServletResponse) res;
response.setHeader("Cache-Control", "no-cache, no-store, must-revalidate");
response.setHeader("Pragma", "no-cache"); // HTTP 1.0.
response.setDateHeader("Expires", 0); // Proxies.
chain.doFilter(req, res);
But it did not work.I also read in one post that if the URL has http then it does not work? Could you suggest how I can avoid this behavior and make the user go to the login page when he clicks on the back button after logout.

I do not know what is the reason of your problem but note that in your web filter you should Skip JSF resources any way the follwing filter is working for me in all .xhtml pages try it
import java.io.IOException;
import javax.faces.application.ResourceHandler;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.annotation.WebFilter;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
* Servlet Filter implementation class NoCacheFilter
*/
#WebFilter(urlPatterns = {"*.xhtml"})
public class NoCacheFilter implements Filter {
/**
* Default constructor.
*/
public NoCacheFilter() {
// TODO Auto-generated constructor stub
}
/**
* #see Filter#destroy()
*/
public void destroy() {
// TODO Auto-generated method stub
}
/**
* #see Filter#doFilter(ServletRequest, ServletResponse, FilterChain)
*/
#Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
HttpServletRequest req = (HttpServletRequest) request;
HttpServletResponse res = (HttpServletResponse) response;
if (!req.getRequestURI().startsWith(req.getContextPath() + ResourceHandler.RESOURCE_IDENTIFIER)) { // Skip JSF resources (CSS/JS/Images/etc)
res.setHeader("Cache-Control", "no-cache, no-store, must-revalidate"); // HTTP 1.1.
res.setHeader("Pragma", "no-cache"); // HTTP 1.0.
res.setDateHeader("Expires", 0); // Proxies.
}
chain.doFilter(request, response);
}
/**
* #see Filter#init(FilterConfig)
*/
public void init(FilterConfig fConfig) throws ServletException {
// TODO Auto-generated method stub
}
}
