Logout Issue C#

[JR]

Hi, i've made a few pages. there is a master page, which contains the design and a loginview control which has a log out button on the logged in template.
then i have a login page, and default page and some other pages that are only for member/admins. Anyways after i press the log out button i made it redirect back to the login page and the user is logged out, i used formsauthentication.signout(). but then i press the back button and it goes back to the previous page and the user is logged in. How do i make it such that after a logout when u press back it wont go back to the page. I looked on google but nothing that was posted worked. I use firefox and vs2008.

The thing is, it might go back to the page, but when they try any functions it will then inform the user that they are logged out.
I don't know much about C#, so I'm just guessing here.

If they "go back", in most cases it doesn't even hit the server -- the browser just loads a page from its cache.

Think of it as me printing out a page, and then logging out. I'm not actually logged in, I just have a copy of what I saw before.

You could try telling the browser not to cache script-generated pages.

i tried to make the browser no cache, but it didnt work. maybe its firefox...
