Here is an example of a complete app: This function does the computation, here it just sleeps for 5 secs def background(): import time time.sleep(5) return "computation result" # this could an image, HTML, JSON, etc... This is the page accessed by the user. The computation is called by an ajax call and executed in background. def foreground(): return dict(somescript=SCRIPT("ajax('background',[],'target');"), somediv=DIV('working...',_id='target'))
