+# Varnish
+
+A reverse proxy server that is used as a cache mechanism for Apache page requests. Varnish listens on port 80, but it can be bypassed by directly accessing Apache on port 8080.
+
+The Varnish secret key for the box is 04788b22-e179-4579-aac7-f3541fb40391, you will need this when using the Varnish modules in Drupal.
+Also you will need to select 3.x as your Varnish version and set the Varnish Control Terminal to be 127.0.0.1:6082.
+
+This module can be found at [https://www.drupal.org/project/varnish/](https://www.drupal.org/project/varnish/)
