Hi all, I have 6 dsl. 4 dsl lines are connected to individual machine configure as proxy-only with null cache_dir, This 4 machines are connected to a main machine configure for round-robin, In this case subscribers only access the main proxy. This are my questions, How many parent proxy can I connect for round robin to the main proxy? with multiple parent proxy does it affect the speed of web page accessing? Thank you, Wennie
