# frozen_string_literal: true

# This module removes the X-Sendfile-Type header for /admin/sidekiq
# assets since Workhorse isn't always guaranteed to have the assets
# present on disk, such as when using Cloud Native GitLab
# containers. These assets are also small and served infrequently so it
# should be fine to do this.
