Jupyter Server Proxy

Jupyter Server Proxy is a Jupyter server extension that enables running arbitrary external processes (like RStudio, Shiny Server, Code Server) alongside a Jupyter notebook server and providing authenticated web access to them via proxied paths (e.g., /rstudio). It comes bundled with a JupyterLab extension to launch pre-defined processes. The current version is 4.5.0, and it generally follows a regular release cadence with bug fixes and new features, with major versions indicating potentially breaking changes.
