from this commit, if you want reverse proxy to sub-directory like `alist` with `nginx`, you need config:
```nginx
location /alist/ {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Range $http_range;
proxy_set_header If-Range $http_if_range;
proxy_redirect off;
proxy_pass http://127.0.0.1:5244/alist/;
# the max size of file to upload
client_max_body_size 20000m;
}
```
