I'm trying to implement server side LB with SpringCloudGateway and Eureka. I have microservices ABC (abc.test.com) and gateway (gateway.test.com) register in eureka (eureka.test.com) by hostname.
If I send request from postman on local machine to gateway.test.com/test/owned then I see in postman console 2 requests instead of 1. Even though I don't have a dependency: spring-cloud-starter-loadbalancer It is look like spring doing client side load balancing instead of server side. Also, not all headers are probably passed through this redirect (like Authorization, which caused final 401).
网关路由：

- id: ABC
  uri: lb://ABC
  predicates:
    - Path=/test/**

当我在localhost中运行服务时-比如说网关8080，abc 8081，eureka 8082，然后通过网关发送请求，它似乎在工作（只有1个请求在 Postman 控制台中，没有客户端可见的重定向）。
当我将网关路由从lb：//ABC直接更改为https://abc.test.com时，它似乎工作正常-但此变通方案无法接受，因为它会取消微服务责任。
我想要实现的是完全的服务器端负载平衡-〉每个通过网关发出请求的客户端都不应该知道网关服务调用了什么/在哪里。
