Static content with base_url

[echarles]

Current behavior when you run with a base_url with jupyter server --ServerApp.jpserver_extensions="{'simple_ext1': True}" --ServerApp.base_url=/my_prefix

• Custom handler are served behind /my_prefix the http://localhost:8888/my_prefix/simple_ext1/default
• Static content is not served behind /my_prefix http://localhost:8888/static/simple_ext1/home.html

I can understand static content is nicely segregated by /static/extension_name/... but with reverse proxy, deployments typically serve all content (static + dynamic) behind a fixed prefix /my_prefix which is not the case here.

Do we keep this like that or do we evolve to /my_prefix/static/extension_name/...?
Based on the decision, we will need to fix JupyterLab.

I agree, base_url should always take priority, such as /myorg/static/lab, and /myorg/lab.

This is on the jlab critical path. @Zsailer If the changes are not too difficult, just gimme pointers and I can open a PR. If the changes are large, maybe I will leave it to you if you have time...

I think it's a simple fix. I'm diving into it now
