pressing back button after logout shows loggedin contents
Joined: Jan 09, 2009
I am developing a website using struts2.
The website has login and logout functionalities.
After i logout i clear and invalidate my sessions, but if i go back to the previous page (with the browser back button), i am still able to see the previously logged in pages.
For example: I have a 'userName' session field in each page. On login the userName is set. On logout as the session is invalidated, the userName is set to null. But when i go to the previous page, i still see the userName set to the logged in value.
How do i prevent this and cause the page to be sent from the server. Thank you in advance
Are you actually using that code?? Its not valid HTML. You have a head tag after body tag, I can't see the starting html tag (I'm sure its there but you forgot to paste it here). If you check the link here, you only need to put 3 lines in the head tag of your html page. Nothing else is needed. The 3 lines are as follows
