Tweaks for RStudio Server Open-Source?

I'm applying the code in this repository to successfully use auth0 as the reverse proxy for Shiny Server. Works like a charm. Are there any modifications necessary to make it work with RStudio Server (the open-source version)? Obviously, the SHINY_PORT environment variable would need to change, to reflect the port where the RStudio Server listens, but is there anything else? For example, is the "/reports" route somehow specific to Shiny Server?

Thanks,
Justin
