Free up mashup resources and XRF_KEY handling

[virilo_tejedor]

I created a mashup and I'm serving it as an IFRAME on a python web server (example here)

This interesting video shows how to free up hidden charts hypercubes during pagination.

Using javascript, it calls to chartX.close() to release QlikSense resources from the browser

Is there any way to free up memory from the server side?

Instead of closing every single chart, how could I free up for the whole user session? Perhaps a release by XRF_KEY

Another question, regarding XRF_KEY, should I handle from the web server a different XRF_KEY for each browser session?

Thanks!

Hi @virilo_tejedor , using close method is the correct way for clean up memory, you don't have to do anything than that.
There is no methods for closing all the objects at once, you have to loop over your active visualizations and then close them one by one.

What do you mean by XRF_KEY?
