Plugin to set Jekyll/WEBrick to not send Cache-Control header field

jekyll-webrick_no_cache_control.rb

# frozen_string_literal: true

# use this with a jekyll site during developement while using `netlify dev` for local testing.
# tested with Jekyll 4.1.1
# plugin needed until this pull request is merged: https://github.com/jekyll/jekyll/pull/8331
#
# this disables Cache-Control header from WEBrick, so that netlify Cache-Control can be set.
# add this file in the site's top-level/_plugins directory.
#

# this will throw a warning about duplicate definition of DEFAULTs, because there are two frozen definitions.
# but the first frozen definition will win.
