Under Development

Implements ideas posted on http://moprea.ro/2011/feb/16/magento-performance-optimization-varnish-cache-2/ and http://www.kalenyuk.com.ua/magento-performance-optimization-with-varnish-cache-47.html.

Features

1. Enable full page caching using Varnish, a super fast caching HTTP reverse proxy.
2. Varnish servers are configurable in Admin, under System / Configuration / General - Varnish Options
3. Automatically clears (only) cached pages when products, categories and CMS pages are saved.
4. Adds a new cache type in Magento Admin, under System / Cache Management and offers the possibility to deactivate the cache and refresh the cache.
5. Notifies Admin users when a category navigation is saved and Varnish cache needs to be refreshed so that the menu will be updated for all pages.
6. Turns off varnish cache automatically for users that have products in the cart or are logged in, etc.)
7. Default varnish configuration offered so that the module is workable.
