README

A local extension which installs StaticFileCache and overwrites some defaults.

Overrides

Default Caching Setting

This sets the default caching to off, so we can select which pages to turn it on for, instead of the other way round

HTACCESS

This is the code needed to be added to the .htaccess / apache config when installing (as found in their docs).

The be added just before the final TYPO3
