Hi Tx for the suggestion but how do I reload a page after eg 30 seconds? Is there no mechanism that when the background tasks finishes to have a web page called which could display the results? I had a look at the signal mechanism of Django but I think that is not working since the background task is in another environment than the django apps which called it.
