shiny server pro: default timeouts?

[Dean Attali]

In the docs for shiny server it says that app_idle_timeout and app_session_timeout have no default. Does this mean that an app and a session will never time out? Or is the default just not shown?

I have the exact same question. By the current looks of it, the app never times out! Dean, have you been able to find a solution to this? It would be really helpful if you'd share any insights on this. Thanks

Haven't looked into it since posing the question, sorry.

The default timeouts appear to be 60 seconds for app_init_timeout, and 5 seconds for app_idle_timeout. Really strange that they are not documented properly.

Joe,

These default timeouts are only applicable for Shiny Server PRO not for the regular shiny server.

Hmmm, what makes you say that? I'm looking at the code for the open source version.

https://github.com/rstudio/shiny-server/blob/431144b20176fa475afa3420a8d42da5f749aeec/lib/router/config-router-util.js#L35-L36

I have an app hosted on the open source shiny server with the below shiny-server.conf file.

# Instruct Shiny Server to run applications as the user "shiny"

run_as shiny;

# Define a server that listens on port 3838

server {

  listen 3838;

 

  # Define a location at the base URL

  location / {

    # Host the directory of Shiny Apps stored in this directory

    site_dir /srv/shiny-server;

    # Log all Shiny output to files in this directory

    log_dir /var/log/shiny-server;

    app_idle_timeout 10;

    # When a user visits the base URL rather than a particular application,

    # an index of the applications available in this directory will be shown.

    directory_index on;

  }

}

Irrespective of the fact that the timeout is set to 10 seconds, it simply does not time out!  I even raised a question on the r studio community and they acknowledged the same.

The idle timeout is for when all users have left an app--after that number of seconds of no visitors being connected, the R process for that app will terminate.

Got it. So there's no way of timing out a session without going PRO.

Thanks for your time.
