Please note: You need at least version 2.0.3 of varnish for purging to work.

Lets purge all blog posts from the cache…

require 'rubygems'
require 'klarlack'

varnish = Varnish::Client.new '127.0.0.1:6082'
# the regexp is not a ruby regexp, just a plain string varnishd understands
varnish.purge :url, "^/posts/.*"

In a Rails app, you might want to use use this in a cache sweeper.

Start up a local varnishd with -T 127.0.0.1:6082. Then run

spec spec

• Support authentication when varnishd is started with -S

• Make parameter manipulation/display more friendly
