[TYPO3] access to files only for authenticated frontend users

[Günter Hipler]

Hello all,

I'm looking for a solution to restrict access to files only for 
authenticated Typo3 frontend users.

Scenario:
- users have to authenticate themselves as authorized frontend users 
(use of newloginbox), so they can see on restricted Typo3 pages a list 
of URLs to files they are allowed to access. Users shouldn't be forced 
to authenticate once more against the Webserver (Apache) after login as 
frontend user in case they access one of the files.
  - But I have to use means of Apache authentication to prevent access 
to these files beside the "Typo3 way" - or are there other possibilities?

Some weeks ago I think I have seen the use of an extension which seems 
to prevent the access to files beside Typo3 without authentication, but 
unfortunately I can't find it again.

Any ideas or hints are welcome!

Günter
