| # 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.
