[TYPO3-english] evil persistent "no_cache"

[Marcel Remmy]

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
typo3/sysext/cms/tslib/index_ts.php
 if ($TSFE->forceTemplateParsing || $TSFE->displayEditIcons ||
$TSFE->displayFieldEditIcons) { $TSFE->set_no_cache(); }
