You can specify the action the server takes when a request matches the access control rule.
Allow means users or systems can access the requested resource
Deny means users or systems cannot access the resource
The server goes through the list of access control entries (ACEs) to determine the access permissions. For example, the first ACE is usually to deny everyone. If the first ACE is set to continue, the server checks the second ACE in the list. If that ACE matches, the next ACE is used. If Continue is not selected, everyone is denied access to the resource. The server continues down the list until it reaches either an ACE that does not match or an ACE that matches but does not continue. The last matching ACE determines if access is allowed or denied.
