I whipped up a cache-buster for Jekyll, similar to the jekyll-assets method. Basically, when you run `jekyll build`, cachebuster.rb generates a hash based on the current time, and shoves it into the default.html template. Requests for style-{hash}.css are redirected to style.css by .htaccess
RewriteRule (.+)-[a-zA-Z0-9]+(\.(js|css))$ $1$2 [L]
# /_plugins/cachebuster.rb
require 'digest/sha1'
module Jekyll
class CacheBuster < Liquid::Tag
def render(context)
"#{Digest::SHA1.hexdigest(Time.now.to_s)}"
end
end
end
Liquid::Template.register_tag('bust_cache', Jekyll::CacheBuster)
