Describe the bug following up the discussion in https://github.com/spring-cloud/spring-cloud-gateway/issues/3636, it's not yet clear to me if it's an issue, if it's not, I do believe that the behavior should be toggled per route, but as I said in the original thread, I don't know yet which team it does belong to. To Reproduce

  • after the gateway is up, open the browser and type
  • http://localhost:8080/login
    • the output will be spring security default login page, which is what I would expect.
  • open another window in incognito mode
  • go to http://dummy.traefik.me/login (magic DNS that points to 127.0.0.1, needed to reproduce host matching),
    • the output will be spring security default login page, which is unexpected, because it should forward the call to httpbin.org as per route config.

Expected behavior if I go to localhost:8080/login, I expect to see spring security which is working properly. If i go to dummy.traefik.me/login, I would expect the requests being forwarded to httpbin.org.
