Nginx Reverse Proxy Redirect Issues - redirect

Question

I have been struggling with this for some time now. My reverse proxy install essentially looks like this:
global_nginx: http://192.168.115.200/client1/ => docker_nginx: http://localhost:8877/ => docker_app: http://app:8080/
Reverse proxy is working fine, but I have trouble when my app is sending redirects. Essentially the app itself is just a Spring MVC application that redirects as following:
#Controller
public class Ctrl {
#RequestMapping(value = { "/" })
public String redir() {
return "redirect:home";
}
}
The result is that when I browse http://192.168.115.200/client1/ I am redirected to: http://192.168.115.200/home/ but should be redirected to http://192.168.115.200/client1/home/
This is the global_nginx conf:
location /client1 {
proxy_pass http://localhost:8877/.;
proxy_redirect http://localhost:8877/ /;
port_in_redirect off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
}
And this is my docker_nginx conf:
location / {
proxy_pass http://app:8080/;
proxy_redirect http://app:8080/ /;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
}

You need to add the /client1 prefix in your proxy_redirect directive.
Maybe:
proxy_redirect http://$host:8877/ /client1/;
You can have more than one proxy_redirect directive, if you need to match multiple conditions. See this document for details.
