. The so-called stateful proxy is used to make different processing based on different situations. These processing have a positive correlation. For example, if three people send numbers, A needs to pass a number to C through B. In one case, whatever a says, B says the same number to C, which is called stateless proxy; another State is that if a says 1, B will pass to the C Number 2. If a says 2, B will pass to the C number 3, which is a stateful proxy. Some materials have b2bua, which is essent
