BaseURL / root path has changed with port forward in coder-server

[br-barrowkwan]

I am sure I have missed a configuration but not sure which is it.
I am running coder in Kubernetes with nginx ingress. I created a workspace, start coder-server and run tomcat on port 8080 in coder terminal
code-server automatically create the port fowarding with a local address

https://coder.mydomain.com/@barrowk/coder-test.main/apps/code-server/proxy/8080/

when I access my app , eg
https://coder.mydomain.com/@barrowk/coder-test.main/apps/code-server/proxy/8080/test/helloworld

this works fine. however, all links inside this page has broken because it points to the coder server url.

eg
https://coder.mydomain.com/@barrowk/coder-test.main/apps/code-server/proxy/8080/image/abc.png

become

https://coder.mydomain.com/image/abc.png

the proxy part "@barrowk/coder-test.main/apps/code-server/proxy/8080" has removed by the port forwarding.

I think you can make this work by:

1. Using absproxy instead of proxy (absproxy does not rewrite the URL, so it is necessary for apps that do not work relatively).
2. Passing --abs-proxy-base-path /@barrowk/coder-test.main/apps/code-server to code-server.

So, https://coder.mydomain.com/@barrowk/coder-test.main/apps/code-server/absproxy/8080/image/abc.png for example should work after that, I believe.

Unfortunately, the ports panel always uses proxy, not absproxy, so you have to manually type it in the URL. I think there is a feature request to allow choosing which to use from the ports panel.
