Maybe - we've not tried it, but I just asked Justin who architected sso, and he suggested that maybe
https://github.com/buzzfeed/sso/blob/master/internal/proxy/o... could be used.
However there would be some caveats - like for example `skip_auth_regex` (see https://github.com/buzzfeed/sso/blob/master/docs/sso_config.... ) would not work with this, because the original URI would not be checked.
