Implementation of the CloudFlare Client Interface API for TYPO3:
- Clear cache for current or arbitrary domains when invoking "Clear all caches"
- Out-of-the-box support for Flexible SSL (https on CloudFlare, http on your server)
- Toggle "Development mode" for your CloudFlare zones
- Possibly restore the originating IPs (REMOTE_ADDR) if this cannot be done at the Web Server level
