Hi Marcel,
If you have an active BE session, your pages won't be cached. This is normal. Did you use to have the no_cache as a URL parameter in the past? If so, it might still linger in the RealURL path cache.

some additional info:

it's a TYPO3 4.2.6 with recent realurl and templavoila! setup.

the root of all evil seems to be this line in
 if ($TSFE->forceTemplateParsing || $TSFE->displayEditIcons ||
$TSFE->displayFieldEditIcons) { $TSFE->set_no_cache(); }
