Keep route prefix when using route in App Platform

I have a spec app.yml that I use to setup a service and a frontend in the App platform (I trimmed down the yaml file):

name: airmeeple

- name: frontend
  source_dir: frontend
  - path: /

- name: backend
  source_dir: backend
  - path: /api

When DO re-routes requests to the backend, it strips the prefix /api such that if the request, the service will receive the request /user.

Is it possible to configure the reverse proxy such that the prefix is kept when rerouting the request, such that the service sees a request with the path /api/user?

Thanks in advance!

@yehudi @mirkul This was added by DO, there is now a preserve_path_prefix when configuring a route that allows the prefix to be kept.

Hey @Longwelwind,

it looks like our backend infrastructure is currently going to rewrite the host to “/” when making a routeable upstream for all services. I hear you about wanting to retain the path. I think when our team first built this, they expected that you would want to have your application route for itself, but I think your suggestion is totally valid. Currently, we always rewrite the host for apps, but I’ll see about implementing this customization.

Same here. Please answer

Did you ore anyone find out a way to perform this ?

I am facing the same issue and am unable to perform what I need to do without that feature.

Thanks in advance.
