Hi All, I'm using dispatcher succesfully, with round robin alg (option 4), and also use ds_mark_dst and ds_next_dst to select other proxy in case of failure. It balances great when all servers are active, but when there are inactive servers, round robin alg selects the next in the round, even if it's marked as inactive. This results in going through ds_next_dst, and overloads the first active server in the dispatcher file until completing the round. Then, other active servers are called, and when passing to a group of inactive servers, starts going through the first active (as much times as inactive servers there are), and again completing the round. Does anyone know a way to implement a round robin aware of inactive servers? Thanks in advance, Francisco Ivandic
