After making a Web cluster, you will certainly first consider the session synchronization problem, because after load balancing, the same IP access to the same page will be assigned to different servers, if the session is not synchronized, a login, one will be logged in state, and not login status. So this paper gives three different ways to solve this problem according to this situation: first, the use of database synchronization session I didn't u
