From df1653174be233f2737d8ec281325dee54011947 Mon Sep 17 00:00:00 2001 From: Eugen Rochko Date: Thu, 19 Nov 2020 17:38:06 +0100 Subject: Add cache buster feature for media files (#15155) Nginx can be configured to bypass proxy cache when a special header is in the request. If the response is cacheable, it will replace the cache for that request. Proxy caching of media files is desirable when using object storage as a way of minimizing bandwidth costs, but has the drawback of leaving deleted media files for a configured amount of cache time. A cache buster can make those media files immediately unavailable. This especially makes sense when suspending and unsuspending an account. --- app/workers/cache_buster_worker.rb | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) create mode 100644 app/workers/cache_buster_worker.rb (limited to 'app/workers/cache_buster_worker.rb') diff --git a/app/workers/cache_buster_worker.rb b/app/workers/cache_buster_worker.rb new file mode 100644 index 000000000..5ad0a44cb --- /dev/null +++ b/app/workers/cache_buster_worker.rb @@ -0,0 +1,18 @@ +# frozen_string_literal: true + +class CacheBusterWorker + include Sidekiq::Worker + include RoutingHelper + + sidekiq_options queue: 'pull' + + def perform(path) + cache_buster.bust(full_asset_url(path)) + end + + private + + def cache_buster + CacheBuster.new(Rails.configuration.x.cache_buster) + end +end -- cgit
