Say I have a website http://example\_dot\_com and I want to use Dash to show some nice graphs. I want to host these graphs under http://example\_dot\_com/cool\_data. I don’t want to re-build my entire website using dash. I was thinking that I could use nginx to specify a proxy such that /cool\_data goes to host\_running\_dash:8050. I have gotten that part working using this slightly adapted example from the gunicorn website:
```auto
server {
listen 80;
server_name example_dot_com;
location /cool_data {
proxy_pass http://127.0.0.1:8050;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
```
The problem now is that the client is making requests for things like `/_dash-dependencies` and `/_dash-layout` rather than `/cool_data/_dash-dependencies`. I’m assuming that these requests are based on the content that is being returned when http://example\_dot\_com/cool\_data is visited. Is there any way to inform Dash that it’s being hosted under a different URL? Or is my strategy here totally wrong?

Hey, welcome to the forums!
Yep, there’s a `Dash` class initialisation parameter for changing the request URL prefixes, for just this situation.
Dash has both `requests_pathname_prefix` and `routes_pathname_prefix`. By adding the prefix in nginx, you have effectively set `routes_pathname_prefix` to be `/cool_data`. So now you need to changed `requests_pathname_prefix` to match this.

Thanks for your response @nedned. I ended up with this:
```auto
pathname_params = dict()
if my_settings.hosting_path is not None:
pathname_params["routes_pathname_prefix"] = "/"
pathname_params["requests_pathname_prefix"] = "/{}/".format(my_settings.hosting_path)
app = dash.Dash( __name__ , external_stylesheets=external_stylesheets, server=server, **pathname_params)
```

Great!
You can also omit setting `routes_pathname_prefix`, you just need to set `requests_pathname_prefix`
