TypoScript

You can disable the StaticFileCache by adding one line of TS:

config.tx_staticfilecache.disableCache = 1

This is also useful, if you want to disable StaticFileCache for specific page types or other conditions. https://docs.typo3.org/m/typo3/reference-typoscript/master/en-us/Conditions/Index.html#gettsfe

[getTSFE().type == YOUR_TYPE_HERE]
