You may advice me Mr Amos about the best choice :) =========================== now , after all of modification i did, i mean after i used squidguard 1.5 beta , i will post my logs of squidguard and cache..log note that im still using squid 3.1.0 , i downloaded it by yum install ! ============================ squidguard.log *2013-02-25 03:09:01 [8261] WARN: Possible bypass attempt.
