I need a rule to block the following Apache log entries,

We are running Plesk 8.6 + Centos and ASL
Plesk calculated the below log entries as http outgoing traffic and the domain ended up with a 16TB traffic total for the month

Please assist with a rule to stop Apache logging these entries, or is their perhaps a better way of avoiding these types of DDOS attacks.

Thanks
