[TYPO3-core] RFC 15286 : Feature: Deactivating the cache menu for admins

[Stefan Sprenger]

Hi Christian,

thanks for your feedback!

By using XCLASS I may improve the mentioned database queries and fix the issue, but, as you wrote, the code will depend on the currently used database, which is IMHO a no-go.

Furthermore, I think, that this feature is needed for every large TYPO3 installation. Based on this, I'd be happy, if it gets part of the TYPO3 core.


Best regards

Stefan
