Hi, Actually, my question was regarding an infrastructure set-up. As an administrator, I want to keep track of calls being made, hence, I would like to put a stateful proxy in place. In such a situation, the overloading of servers is an imminent threat, since stateful proxies have less capacity(load wise) than stateless.. BTW, is der a way to combine a stateful proxy and several stateless proxies to do something useful?? As in a master-slave kinda thing?
