I have read about Authoriztion in Apache: Require host example.org Require host .net example.edu This configuration will cause Apache to perform a double reverse DNS lookup on the client IP address, regardless of the setting of the HostnameLookups directive. 1- What is the DNS that Apache ask for the IP of the client ? 2- Can I change it to let Apache ask a custom DNS ( somehting like DNS-SERVER-IP 192.168.1.10)? --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
