Solution : Varnish Vanish (Orignal by Chris Delalis)
Contacts a Varnish server with a cache clear request over HTTP on the following actions:
- Drupal Cache Flushes
- Node Saves
- Node Updates
If the Web Experience Toolkit (WxT) distribution is installed, the WxT render caches will also be cleared, primarily so that menu updates will be reflected after a varnish cache clear.
