how to log off the user when he hits the back page???

[MackAA]

I disabled the back button with disabling the page's cache. But when I refresh the previous page I get a postback and sessionid has the same value, so I still logged on. Is anyone could tell how to make the user logged off every time he hits the back page button?

Messing with the browser's back button is not a very good idea. I would complain to you and would not use your app or visit the site.

You can use a session value and redirect to another page.

Hello dvannoy,

The problem actually is: when you move from my app and you come back to using the back button, there any server event fired. I don't how to do to catch the event (back button) and set a session value

 

[dvannoy]

you need to pass a session from page to page.

then when they logoff set the session to something else like "" or maybe a number that represents them being logged off.

You cannot disable the back button period.

Hello dvannoy,
Thanks for your help.

I already checked out this article and I understood what you want me to do to reslove the problem. But I still get the issue because I can't change the value of session variable when user move from my app by writing in the adress bar a different site's url. When closing the window or when clicking to loggoff every thing is fine.

In my case, the article

doesn't resolve the problem beacuse the connected user could navigate in the app and visit more than one time each page.

Actually the issue is: there is no any server event fired when moving from my app by navigating to another site. So, by back button (if cache is not disabled) the user could get the previous page and he still connected. If cache is disabled, the back button displays an IE page and when refreshing the previous page is displayed as well.

I hope you catch me!
