.. _Tsfe-softDisableCache:

==============================================
Tsfe::softDisableCache()
==============================================

\\nn\\t3::Tsfe()->softDisableCache(``$request = NULL``);
----------------------------------------------

Deactivate cache for the frontend.

"Soft" variant: Uses a fake USER_INT object so that already rendered elements
elements do not have to be rendered again. Workaround for TYPO3 v12+, since
TypoScript Setup & Constants are no longer initialized when page is
completely loaded from the cache.
