Hi John
you are not very specific about the setup you plan to run.
I'm successfully using Apache as reverse proxy to forward requests to shiny-server.
http://myhost/shinyApps/ gets proxied to
http://myotherhost:3838/ where shiny is listening.
Another setup would be to run shiny-server on a different port on the same server.
In my experience it works very smoothly, with one exception:
Using shiny-server open source it is difficult to pass information from Apache to the shiny-app. Most header fields are filtered (in particular REMOTE_USER).
Hope this helps.
