Passing headers. VScode to Colab Enterprise/JupyterLab with authentication + CORS

[gogasca]

Currently I want to connect VScode with JupyterLab extension to Google Cloud Colab Enterprise or AI Notebooks or any JupyterLab service that requies authentication.
I'm currently using JupyterLab Gateway as a way to overwrite headers (Authentication + CORS - Origin). Is there a way to overwrite HTTP headers in current Extension? If not what is the any good pointers for me to add support for this.

Background:

• Pass session ID during Websocket Upgrade connection when using Gateway. jupyter-server/jupyter_server#1439
• https://medium.com/@gogasca_/how-to-connect-from-vscode-to-vertex-notebooks-directly-8c078d538b0b

Wanted behavior:
Ability to pass custom HTTP header for HTTP(s) and Websockets. Example:

headers = {"Origin": PROXY_URL, "Authentication": AUTH_TOKEN}

• Some headers like Authentication can be regenerated every X seconds. (Using an external command gcloud)

I would like to see how can I add this to Extension properties. Any pointer will be appreciated

@gogasca Thanks for filing this issue.
At this stage we have no plans on supporting such a feature request.
However you can create your own extension that passes the necessary headers and the like.
Please have a look at the Jupyter Hub extension that we've created.

This is a simple extension that takes care of auth and the like (with custom headers).

Feel free to reach out for additional details with regards to this extension or the like
