This is a slightly refreshed approach to the plugin mentioned by the SAP Documentation. I wanted to have a look at how FLP Plug-In development works in general.
For the purpose or using this Repository as a starting point at any time, I've kept the getRenderer
function as well as some of the dummy code from the generator.
This Plug-In is supposed to keep the FLP sessions alive by sending small (HTTP HEAD) requests in an interval to the SAP system. Be aware though that before using something like Plug-In development to do this, there are various ways to go about this. One approach could be using the native "Gateway Time-Out Warning" settings explained here. Also mentioned in SAP OSS Note 3248472 and 2955208.
It'd be basically the same as described here.
I'm not sure how to 'Make sure that your plug-in is robust if more than one instance is loaded'. Is it something that is done from within the Plug-In scope itself or do we have to go into the window scope here (i.e. the "sap-ushell-config"?). You'd have to take a look into the SAP Standard plugins or other comparable ones.
As the docs state:
Even if your plug-in implementation is a singleton by nature, multiple instances might be created due to configuration, and your plug-in must be able to handle this in a robust way.
If you know the answer: DM me anywhere or open an Issue/PR. I'd love to know.
