Caches the result of proxy calls allong with the fingerprint of their inputs. If the inputs remain the same, uses the cached version.

Add this line to your application's Gemfile:

gem 'middleman-caching-proxy'

And then execute:

$ bundle

Or install it yourself as:

$ gem install middleman-caching-proxy

In config.rb:

git_head = `git rev-parse HEAD`.chomp

activate :caching_proxy, cache_key: git_head

things = [...]

things.each do |thing|
  proxy_with_cache(
    path: "/things/#{thing.slug}",
    template: "/templates/thing_template.html",
    proxy_options: {locals: {thing: thing}},
    fingerprint: thing.updated_at.to_i
  )
end

There are 4 required parameters:

• path: the page path,
• template: the page template,
• proxy_options: options to pass to the proxy invocation,
• fingerprint: a value that indicates the 'version' of the item. If this value changes, the cached version will be skipped and updated.
