Currently when user logs out and hits the back button of browser it show the page error.html page which I have mentioned in web.xml. this html page has a link to main_menu.do.
Right now when user clicks the above link it does not take him anywhere and stays there.
I want to send user back to login page if he is logged out. but i cannot give link to login.do instead of main_menu.do because this page is being used by other server errors too and it takes user back to main menu page.
Where should I add code to check if user has logged out and send him back to login page if he clicks main_menu.do link in error page?
I have tried to debug it....but it's not going to the action where I can write some code to check it...it just refreshes the same page.
