Varnish Caching sends a PURGE request to Varnish Cache when a page or post is modified. This occurs when editing, publishing, commenting or deleting an item, and when changing themes. Not all pages are purged every time, depending on your Varnish configuration. When a post, page, or custom post type is edited, or a new comment is added, only the following pages will purge: * The front page * The post/page edited * Any categories or tags associated with the page Varnish Cache is a web application accelerator also known as a caching HTTP reverse proxy. You install it in front of any server that speaks HTTP and configure it to cache the contents. This plugin does not install Varnish for you, nor does it configure Varnish for WordPress. It's expected you already did that on your own using the provided config files.
