Ipecache

Ipecache is an extensible tool for purging URLs from Caches and CDNs.

Installation

Gem Install (recommended)

ipecache is available on rubygems. Add the following to your Gemfile:

gem 'ipecache'

or install the gem manually:

gem install ipecache

Ipecache Configuration

Ipecache will not work with no configuration, so before you can purge anything, you'll need to specify some configuration for the plugins you wish to use.

Ipecache will look for a configuration file in the following locations, in ascending order of precedence:

  • /etc/ipecache-config.yml
  • ~/.ipecache/ipecache-config.yml

Anything set in the configuration file in your home directory for example, will override options set in /etc.

Below is a sample config file with all supported options and all shipped plugins enabled below, followed by an explanation of each section.

Please note, if you do not want to use a particular plugin, don't specify any configuration for it and it will automatically be disabled.
