What's It All About

The following files are avialable:

• src/BlackListService.php - A simple service that identifies all IP addresses that are not 127.0.0.1 as blacklisted.

• src/EventSubscriber.php - A service that subscribes to kernel.request events and utilizes the blacklist service to determine if a requesting IP should get an access denied response. It will only be denied if the request is not a Sub Request and is not requesting an admin URL.

• drupal_event_dispatcher_example.services.yml Services YAML file for the example that wires all of the services together and registers the event subscriber via the proper tag.

• drupal_event_dispatcher_example.info.yml Module YAML file.
