[TYPO3-core] RFC #16832: Bug: error when using t3lib_TCEmain->clear_cacheCmd in frontend

[Søren Malling]

This is not a review but a comment on this RFC:

IIRC tcemain is not meant to be used frontend? But, if it is, there
should be the same condition for each and every function in tcemain
using a backend(-user) related function!

Maybe a function/possibility of clearing cache from frontend should be
introduced to a different class (t3lib_div?)?!

Regards

Søren
