The deployment environment is Nginx gunicorn Django

Nginx configuration is as follows

location /app1 {
        rewrite ^/app1/(.*)$ / break;
        proxy_pass_header Server;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Scheme $scheme;
        proxy_redirect off;
        proxy_pass http://11.11.11.1:8001;
}
location /app2 {
        rewrite ^/app2/(.*)$ / break;
        proxy_pass_header Server;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Scheme $scheme;
        proxy_redirect off;
        proxy_pass http://11.11.11.1:8002;
}

app1 and app2 are different applications. The following are the problems encountered

When accessing /app1/test, Django will add slash at the end and redirect. The problem is that it will redirect /test/ instead of / app1/test/
When accessing /app1/admin, it will be redirected to /admin/login/?next=/admin/.

In my own program, for example, when Oauth authentication requires a redirection URI, I think of passing $http_host/app1 through X-host## when using Nginx proxy. # Passed to the backend Django, and then get the real URI.
