README

LiteSpeed Cache integration for TYPO3.

This extension emits LiteSpeed Cache response headers for frontend requests and automatically purges LSCache when TYPO3 caches are flushed.

Features

• Adds X-LiteSpeed-Cache-Control based on TYPO3 cacheability.
• Adds X-LiteSpeed-Tag derived from TYPO3 cache tags (plus page and site tags).
• Adds X-LiteSpeed-Vary for cookie-based variations.
• Purges LSCache automatically on TYPO3 cache flush events.
• Purges LSCache for specific pages when TYPO3 clears a page cache.

Requirements

• TYPO3 12.4+
• PHP 8.1+
• OpenLiteSpeed or LiteSpeed Web Server with LSCache enabled
