Webservice Authentication: additional json response

#1

Hi there!
Many Thanks for Webserver Auth feature. It is absolutely great!

But is it possible to add some new feature?
F.E.

  1. ShinyProxy sent request to webserver ------>
  2. web server answers: 200 OK PLUS custom_json_field {some string…} ------>
  3. ShinyProxy auth user + recive custom_json_field and send it into container as ENV (just string env, and shiny app developers may use f.e. jsonlite R package to parse this ENV).

I suppose this feature greatly improves functionality and interaction between Auth Web Server and Shiny app with small cost (just get custom json field and sent it into container ENV).

Thank you for your amazing solution!
