extensibility.

WordPress Varnish Purges is a plugin that purges new and edited content, it’s
intent is to be usable for a multi-site installation, to support all necessary
purge orders for wordpress and to be expandable via extensions.

taken. This plugin supports what is called extensions that can be added to add
special purges for specific wordpress plugins.

This plugins is mainly aimed at multi-sites installations (but can be used on a mono site installation) and requires some knowledge about varnish and vcl files.

FAQ

When will be V1.0 be relased

This plugin will be in fully tested V1.0 by end of may 2011.

Does this just work?

Yes. Exdtensivly tested in multi-site with sub-domain install. But has to be
tested in non sub-domain (site.com/blogname)

But how should my varnish configuration file look like?

I have provided a simple VCL that can be used as a reference.

Does it work for Multi-Site (or WPMU)?

Yes. Activating the plugin site-wide will provide the functionality to all
blogs. Edit wp-config.php and
include these lines just before “That’s all, stop editing!” message:

global $varnish_servers;
$varnish_servers = array(‘192.168.0.1:80′,’192.168.0.2:80’);
define(‘VARNISH_SHOWCFG’,1);

The varnish servers array will configure multiple servers for sending the
purges. If VARNISH_SHOWCFG is defined, configuration will be shown to all
users who access the plugin configuration page (but they can’t edit it).
