Another Typo3 CDN integration option is to use the cs_cdn extension which is based on smile_cdn. This extension replaces local file references with references to remote files, overwrites file links, and can delete KeyCDN files from cache.

Supercharging Typo3 with a CDN Integration

With KeyCDN, supercharging your Typo3 Installation is done in a variety of ways.

  • KeyCDN offers HTTP/2 support on all edge servers to help improve speed and optimize content delivery.
  • Access to a global network of POPs allows site owners to deliver content to users faster. For large enterprise customers, this not only helps reduce latency but is also cheaper.
  • Instant Purge ability allows customers to purge by tag, by URL, or purge everything. It only takes a few seconds until the cache is globally purged on all POPs.

KeyCDN also offers many additional features and provides a list of useful tools to do everything from site speed tests to HTTP/2 server checks, and much more.
