idea : support for UNIX sockets

[jhgoebbert]

Hello everyone,

Running web applications on multi-user systems (even behind a JupyterHub) requires that the web application supports some kind of authentication (this can be a token that has to be passed in the URL, as we know it from Jupyter/JupyterLab).

However, some applications lack this basic security and are accessible to anyone who can log into the multi-user system and access their port.

If these web applications would not use a port but a UNIX socket for internal communication with jhsingle-native-proxy, this security hole could be closed in a quite elegant way.
For jupyter-server-proxy this great feature was just recently added - jupyterhub/jupyter-server-proxy#321 and might be a starting point.

Yes, this project was originally a fork of jupyter-server-proxy so it makes sense.
