As part of my ongoing conversion from dynamic to static sites using Jekyll, a requirement recently came up to put all static files on the Rackspace CloudFiles service via their CDN integration. The logical solution to this was to write a plugin.
I looked at several ways of doing this, but the best way appeared to be adding a tag to the Liquid templating system. The plugin is up on GitHub and should be pretty simple to use. I’m currently using it on one site I’m developing but expect to be using it on a few more over the next few months.
