Struts back button problem after logging out from an application

[Deepaks Deshpande]

Hi,

I have created a struts application where in, I have a login page, home page some link on the home page and a logout link.Everything else is working properly except for whenever i have logged out from the application, and i hit the browser's back button i am redirected to my home page. I tried adding the following code in the header section of my jsps, but it doesn't work

  
response.setHeader("Cache-Control","no-cache"); //Forces caches to obtain a new copy of the page from the origin server
response.setHeader("Cache-Control","no-store"); //Directs caches not to store the page under any circumstance
response.setDateHeader("Expires", 0); //Causes the proxy cache to see the page as "stale"
response.setHeader("Pragma","no-cache");   

How to overcome this problem?

Thanks in advance.

Are you using sessions to maintain the state? Are you invalidating the session after logout?
