How to serve Askbot under a subpath in NGINX?

edit

If I understand you, that's what I think I'm doing, without success. When you say, 'edit the settings.py', do you mean something more than that ASKBOT_URL or ASKBOT_APP_URL? When you say, 'edit the nginx virtual config', do you mean something like:

upstream askbot {
   least_conn;
   server askbot:8000 weight=10 max_fails=3 fail_timeout=30s;
}

server {
   listen 443 ssl;
   server_name root.foo.bar;
 
   location /askbot {
      proxy_pass                  http://askbot;
      proxy_set_header            Host $host;
      proxy_set_header            X-Real-IP $remote_addr;
      proxy_http_version          1.1;
      proxy_set_header            X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header            X-Forwarded-Proto https;
      proxy_redirect off;
   }

   location /m {
      proxy_pass                  http://askbot;
      proxy_set_header            Host $host;
      proxy_set_header            X-Real-IP $remote_addr;
      proxy_http_version          1.1;
      proxy_set_header            X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header            X-Forwarded-Proto https;
      proxy_redirect off;
   }
