• code-server version: 1.0.0
• OS Version: Debian 9, With docker deployment

Steps to Reproduce

1. Setup Nginx reverse proxy to a different path - i.e. to something.something.com/vscode/
2. Login works fine, but upon vscode page, it's just a blank page. Client browser console shows its trying to connect to wss://something.somthing.com/, without the correct root-relative path (something.something.com/vscode/), which.... obvious will not work.

Also, I did not find any documentation (or config in general) related to this type of deployment... guess that probably can be improved a bit?
