The latest version at mybinder.org works, unless one sets urlpath=rstudio. It causes the binder URL to have a path of /user/reponame/rstudio?token={token}/auth-sign-in... which results in a 502 HTTP error. Rather than concatenate the /auth-sign-in portion to the request uri, we need to parse the latter and append the Location header value to just the path and not the whole uri.
Expected behaviour
You set urlpath=rstudio at mybinder.org rather than launch Jupyter Lab and then start RStudio.
