I would like to be able to host Aspire Dashboard behind a reverse proxy such as NGINX. Unfortunately, Aspire Dashboard doesn't take X-Forwarded-* headers into consideration, and doesn't allow to configure a path base.

As an example, assume Aspire Dashboard is accessible internally from http://aspire-dashboard-service:18888/ and externally from https://example.com/dev/aspire-dashboard/ through a reverse proxy.

The issue of the path base has already been described in #4528 and #4159. Additionally, authentication through OpenID Connect fails to set the correct value for redirect_uri, as it uses the internal schema (HTTP) rather than the external one (HTTPS).

Describe the solution you'd like

It's possible to add support for reverse proxies and load balancers as described here:
https://learn.microsoft.com/aspnet/core/host-and-deploy/proxy-load-balancer

Ideally, all the featured described in previous page (except for certificate forwarding) should be configurable by the user, namely:

• Forwarded headers from the reverse proxy or load balancer
• Header names, known proxies and forward limit
• Forcing the assumption that external address is always HTTPS (necessary when the reverse proxy does not support X-Forwarded-* headers)
• Path base

I created a PR for this #6963

Keeping in mind that PR #6963 only adds "path base" support. This is not sufficient to close the issue described here.
