-# Dev-server-only fix: WEBrick's FileHandler#not_modified? treats a Range
-# request's If-Range header the same as If-None-Match, replying 304 (no body)
-# instead of 206 with the requested bytes. Browsers rely on ranged requests
-# (with If-Range) to fetch a video's trailing moov atom when seeking/loading
-# metadata, so this breaks video playback under `jekyll serve`.
-# See https://github.com/ruby/webrick/blob/master/lib/webrick/httpservlet/filehandler.rb

-# Upstream bug, not yet fixed as of writing:
-# https://github.com/ruby/webrick/pull/173 (fix if-range returning 304 instead of 206/200)
-# https://github.com/ruby/webrick/pull/169 (do not cache range requests)
-# Drop this plugin once one of those lands in a released webrick version.
