# This class is part of the Gitlab::HTTP wrapper. Depending on the value
|
|
# of the global setting allow_local_requests_from_web_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.
