is used, the Session should not be stored in the process. You must use StateServer or SqlServer for storage. If you stick to the storage in the process, you can choose to use the Client affinity (Client affinity), that is, all requests of the customer have the same server for response and will not be forwarded to other servers, this sacrifices reliability. When the server fails, the request cannot be forwarded to other servers for service. The result is that the client request has no response.
