GateWay lost session in MVC mode

[xiaoege]

My project consists of Spring Cloud Alibaba, Nacos, GateWay, Spring Session. When i make a request to the original path, i can use the Spring Session with the Redis, the session is shared. But when i make a request throw GateWay,i still can get the session from shared redis until use "redirect:/xxx" in MVC mode. In that case, i lost my session and the new session created in redis. I want to know how can i make this in the same session in redis. Thanks.
