Keep session alive for X min, not when the browser is closed or PC is suspended

[JuanmaC]

Hi,

I'm developing an app that will take CSV files from the user and will run some heavy analyses on them, so it will take a while to finish.

Many of the times the user leaves the app running and goes away, hence the PC will enter in suspension/hibernation. Either that or the user closes the browser.

Is there a way keep the session alive for a few hours even though the browser is not open or the user's PC is suspended?

What I've tried:

• The shiny-server.conf is in its default state (as https://docs.rstudio.com/shiny-server/#session-timeouts states).
• I´m not sure how this question applies to my case.
• I created a function with a reactiveTimer to print a cat every X min. It displays the message, but it does not keep the session alive.
• session$allowReconnect(TRUE).
