Hi Steffen,

http://typo3.org/extensions/repository/view/lib/0.0.20/info/class.tx_lib_controller.php/

        // Initialize the cHash system if there are parameters available
        if ($GLOBALS['TSFE'] && $parameters->count()) {
            $GLOBALS['TSFE']->reqCHash();
        }

Currently we do the cHash test by default independently if it is a USER
or a USER_INT. But maybe that is our fault: 

USER + cHash + reqCHash: Fine the page is cached.

USER_INT + no cHash + reqCHash: Also works.

 But: The page should be cached with a marker for USER_INT. Is it?
 Or is it completely rerendered each time because of reqCHash? I am not
 sure in the moment. I fear I need to dig into that stuff again. So
 complicated. So quickly forgotten.


Now the question of a solution: 

I fear with this we have to set reqCHash only if it is a USER object and
unset if for USER_INT. For that the controller needs to find out itself if
it is a USER or USER_INT. But how? Manual setting would be a simple but
ugly solution. Then we would end up with the same confusing settings
like tslib_pibase.
