Cluster Varnish for Joomla
In cooperation with Perfect Web Team Byte developed its own extension for Joomla. With this extension Joomla sites can run on the superfast Byte Varnish Cluster. The extension allows Joomla to generate the proper caching headers generates with TTL ( time to live) information and that specific pages and / or extensions will not be not cached. Also allows the extension to automatically empty the cache for specific pages after changing an article in Joomla and cache the entire site should be emptied after clicking a special button.
NOTE: This plugin requires knowledge of varnish caching and server administration, it will not work out of the box. We recommend proper testing.
