Think about the following: If the user would have saved all pages to disk
he could still view them on the next day - without logging in.

Altough it could be possible you find some HTTP headers forcing the browser
to reload history pages, I guess most browsers implement the "Back" button
like you described.

I just had a look at facebook. There your described behaviour doesn't occur.
You should probably check what HTTP header such applications like facebook,
gmx, etc. are sending, and play around with those.
