WordPress Varnish ESI Widget

This plugin uses WordPress + Varnish and caches the sidebar with ESI.

Why is this approach better than other caching systems?

The worst queries in WordPress are usually contained within the sidebar. If your content is engaging and someone browses from one page to the next, most caching plugins need to generate the page and sidebar on a fresh visit. Since this plugin caches the sidebar separately using ESI, the only queries executed on the second and successive pages is the page content - not the sidebar.

What Plugins break with this?

Any plugin that requires the page to load and not be served from cache will break. Since your page might be served from Varnish, it will never hit the backend server. Statistics plugins are generally affected, but Google Analytics and Pikwik do work properly. Banner ad solutions also need to serve the content through an IFrame or Javascript rather than depending on a pageload.

WP Greet Box and WP Post Views are known to break with caching.
