Remove Shiny Server and use only shiny behind a reverse proxy

[MickPetit]

Hello,

I'm new in Shiny world (less then one year). I've create some apps that works on shiny server with an architecture like that :

user -> Apache Reverse Proyx -> Dockerized Shiny server with app 1
                                                              -> Dockerized Shiny server with app 2

                                                              ->..................

That's work well.

Now I will need to get some cutom HTTP headers in my shiny apps and the community version has remove this functionality. I know it s possible to put back this functionality but it s the opportunity to try my apps Without Shiny server. (and without others, like shinyProxy).

So I have a new docker with a simple shiny::runapp(), I've configure my reverse proxy in the same way than for shiny server, but the Shiny Apps freeze withe the famous "unable to load http://url/websockets.

Does anyone have a good config for running Shiny behind an apache reverse proxy ?

Regards,

Mick

this is an example of one of my non working apache confs :

<Location "/app/">
      #RedirectMatch permanent ^/app$ /app/

       RewriteEngine on

       RewriteCond %{HTTP:Upgrade} =websocket

       RewriteRule /app/(.*) ws://localhost:49171/$1 [P,L]       

       #RewriteRule /app/websocket/(.*) ws://localhost:49171/$1 [P,L]

       RewriteCond %{HTTP:Upgrade} !=websocket
       RewriteRule /app/(.*) http://localhost:49171/$1 [P,L]       

       #RewriteRule /app/websocket/(.*) http://localhost:49171/$1 [P,L]

       ProxyPass  http://localhost:49171/
       ProxyPassReverse  http://localhost:49171/

       #Header edit Location ^/ /app/
       #Include /etc/apache2/docker-conf/common/ldap.conf
