Please help me to resolve this. Thanks in advance.

Hi Jeanne Boyarsky,

i had done this in the way you said.

Thanks Jeanne.

Hi Umamahesh,

Well, but i don't want logout problem. My question was entirely different ....

He asks me the web application has to work like Banks site... means if I refresh or click on Back button(Browser's) then it has to throw the user out of session, I checked lot in internet. But I found like only disabling back button of disabling F5 keys like that. But he’s not accepting that.

Hi Jeanne Boyarsky,

I got your logic, But, I'm getting some what confusion to implement.
In Filter class i written the fallowing code
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException { HttpServletRequest request = (HttpServletRequest) req; //ServletContext context = getServletContext();//getServletContext(); //Get the IP address of client machine. String ipAddress = request.getRemoteAddr(); if(request.getAttribute("tokens") !=null){ System.out.println("First Request"); } String token = generateToken(); request.getSession(true).setAttribute("token", token); System.out.println("Token Generation : " + token); //Log the IP address and current timestamp. System.out.println("IP "+ipAddress + ", Time " + new Date().toString()); chain.doFilter(req, res); } public static final String generateToken() { String token = UUID.randomUUID().toString(); //System.out.println("Token : " + token); return token; }
In this dofiltermethod I'm getting confusing that how to use if condition to check submitted token matches current one.

How to add Token to every JSP
i Just Trying to compare every JSP like in below. But, Not working.

<% if(request.getAttribute("tokens") !=null && !request.getAttribute("tokens").equals(session.getAttribute("token")) ){ System.out.println("Bad Request"); response.sendRedirect("http://www.google.com"); // Say Error Page return; } out.println(request.getSession(true).getAttribute("token")+"<br>"); request.setAttribute("tokens",request.getSession(true).getAttribute("token")); out.println(request.getAttribute("tokens")); %>

one more... <filter-mapping> tag works for request going to server only... means(in our case only error handling with refresh button may work), for back and forward button it will not work.

<filter-mapping> <filter-name>LogFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>


Can you please elaborate some what ....

Hi Seetharaman,

I'm not clear about Duplicate form submission will works for throwing user from out of session. Because Mostly the form submission(Taking Inputs from User) in Banks sites are takes place at the time of transfer funds only. But i want to throw user at any time in the session to Session expire Page if he/she clicks on Browser's refresh button. So then, PRG will not takes place here.Every one implement PRG at the time of user taking inputs and getting results at the same time, nothing any where. But in Banks sites mostly User will give inputs at the time of Fund Transfer only Rest of places i don't think , they will use PRG.

Moreover we are using Struts saveToken(), IsTokenValid() for avoiding Duplicate Form Submissions.

Any Suggestion from You. Please help me if you done these kind of things earlier.

Hi,

If you take ICICI bank or Axis Bank, Or take the India's Most Wanted site www.irctc.co.in
All these sites are working on the same scenario. After successful login.. if user clicks on browser's back or refresh buttons. it throws user to Session expire page.

Hi Jeanne Boyarsky,

Using Token Validation how can we approach. Means.. is there any thing to identify browser refresh button event.
Can you please explain more...

Dear Bear Bibeault sir,

In all Indian Bank Sites, they are fallowing same scenario. I don't know exactly ...But due to security reasons only they are doing like that.. My manager telling it good to implement to provide more security to our site.

Hi Sir Please Help me

Hi Bear Bibeault sir,

My problem is not for after logout. My problem is for user within the session and working with site, unfortunately clicking on refresh or back button. it send him to out of session.

There are some sites which works on the same.



Thanks & Regards,

Udaya Prasad

Hi All,

Thanks for Replying,

I tried a lot with JavaScript ,i think its almost impossible.. because there is no event to identifying browser's back or refresh buttons. And calling AJAX every time for checking user availability also not a good idea(More Hits for server).

Hi William ,
You said Some "back" buttons simply bring up a cached copy of the page without accessing the server

But most Bank site uses below kind of code definitely for cache,cookies removing.

<% response.setHeader("Pragma","no-cache"); response.setHeader("Cache-Control","no-store"); response.setHeader("Expires","0"); response.setDateHeader("Expires",-1); %>

Security Policy:

Same Origin Policy:

Is there any policy kind of settings between browser and web application. i heard one policy like "same origin policy" for security settings..
See if we are using any bank sites for first time in the freshly installed Google chrome browser. It will show like “Your browser settings are changed for this site…” like that for first time use.

Please help me in this...

Dear All,

I got one task from my manager, regarding browser back button, refresh button. He asks me the web application has to work like Banks site... means if I refresh or click on Back button(Browser's) then it has to throw the user out of session, I checked lot in internet. But I found like only disabling back button of disabling F5 keys like that. But he’s not accepting that.

Can any one please suggest me how to approach for this? Can we throw the user out of session when he clicks on browser back button or refresh button.

I think its possible . But i don't know how to implement.

Please help me in this.
