# frozen_string_literal: true
# This class is part of the Gitlab::HTTP wrapper. Depending on the value
# of the global setting allow_local_requests_from_hooks_and_services this adapter
# will allow/block connection to internal IPs and/or urls.
#
# This functionality can be overridden by providing the setting the option
# allow_local_requests = true in the request. For example:
# Gitlab::HTTP.get('http://www.gitlab.com', allow_local_requests: true)
#
# This option will take precedence over the global setting.
