[TYPO3] frontend users - user logged out, pages still in browser cache?

[Tomasz Chmielewski]

I have a slight problem with username/password protected pages.

Overall it works fine, but recently I was notified that the protected 
pages are still in browser cache after user logs out.


For example, let's say we have a Very-Important-Page, protected with 
username/password. User can see it after he logs in, and after he logs 
out, he's redirected to some other page. Everything fine till now.

However, after pressing "back" button in the browser, anyone can see the 
content of this Very-Important-Page, which is of course undesired.


Is there a workaround for that?

I'm using TYPO3 4.1.1.
